Born in Dublin, Ireland, Imelda May is a unique vocal talent, one whose gift lies outside the normal order of pop culture time and trends. Inspired by the sounds of vocal jazz à la Billie Holiday and the sound and looks of rockabilly, May began performing with the swing outfit Blue Harlem, and released a handful of independent CDs before scoring attention in 2007 with her nomination for an award as Best Burlesque Singer as well as the release of her more official debut, Love Tattoo. The album, featuring her strong backing band comprised of players Dave Priseman, Darrell Higham, Al Gare, and Steve Rushton, was critically and commercially well received, leading to some high-profile live gigs, including hitting the road with Jools Holland. It was released in the U.S.A. by Decca in 2009, followed by two singles, and scored a mid-level success. Her sophomore effort, Mayhem, arrived in September of 2010, preceded by the single "Psycho".

In 2001, legendary blues pianist Pinetop Perkins was edging up on 88 years of age when he played the concert date in Chicago documented on this album. Perkins sounds plenty spry here, but this certainly doesn't capture the great man at his best; Perkins was a pioneer of the boogie-woogie style and was a longtime member of Muddy Waters' band, but most of On the 88's: Live in Chicago is devoted to easygoing midtempo numbers that sound a bit timid compared to what he played in his prime. Perkins shows he still had a great touch on this recording, and his timing is more than fine, but his left hand doesn't quite anchor these tunes the way he did in his salad days (it might have helped if he'd been given a better piano for this gig, since the instrument has the tone of a second-rate electronic keyboard), and even if his singing is game, his voice was showing its wear.

Waters' The Real Folk Blues and More Real Folk Blues, combined here onto one CD, were not exactly random collections of tracks – the quality was too consistently high for them to just have been picked out of a hat. Still, it was a pretty arbitrary grouping of items that he recorded between 1947 and 1964. In fact, they hail from throughout his whole stint at Chess, virtually; at the time these albums were first issued, though, all of the material on More Real Folk Blues was from the late '40s and early '50s. They didn't exactly concentrate on his most well-known songs, but they didn't entirely neglect them either, including "Mannish Boy," "Walking Thru the Park," "The Same Thing," "Rollin' & Tumblin' Part One," "She's Alright," and "Honey Bee," amongst somewhat more obscure selections. So ultimately, this disc's usefulness depends on your fussiness as a collector – if it's the only Waters you ever pick up, you'll still have a good idea of his greatness, and if you don't mind getting some tracks you might already have on more avowedly best-of sets, you'll probably hear some stuff you don't already have in your collection.

Joe Louis Walker is one of the most interesting guitarists on the contemporary blues scene, not to mention one of the most prolific; 2015's Everybody Wants a Piece is Walker's 25th album since he made his debut with 1986's Cold Is the Night, and it hardly sounds like the work of someone padding his résumé. Walker is a player who keeps his music lively by mixing up the formula, folding plenty of rock, R&B, and Latin influences into his work instead of laying out the typical 12-bar figures all over again, and Everybody Wants a Piece finds him shaking it up with impressive results, especially on the wah-wah-fortified and rocked-up cover of "Witchcraft," a slinky interpretation of "Wade in the Water" that mixes up gospel and funk influences, the rollicking boogie-woogie of "Buzz on You," and the slide guitar shuffle of "35 Years Old"…

With a passel of familiar faces in the cast (ex-James Brown bassist Tim Drummond, pianist Dumpy Rice, harpist Rusty York), the reclusive Mack rocks up some memorable dusties his way – the Falcons' "I Found a Love," and Bobby Bland's "Share Your Love with Me," Little Walter's "My Babe," and Jimmy Reed's chestnut "Baby What You Want Me to Do," along with his own "Gotta Be an Answer".

It's been so long since B.B. King stepped outside of his comfort zone that One Kind Favor comes as a bit of a shock. Unlike so many albums he's cut in the wake of the crossover success of The Thrill Is Gone way back in 1970, the sound is stripped-back, not splashy, there is not a reliance on guest stars, and the repertoire is pure blues - and these are all songs that he's never recorded before, including three tunes by his longtime idol Lonnie Johnson. Credit for the concept must be given to producer T Bone Burnett, who applies a similar neo-rootsy aesthetic to One Kind Favor that he did to his production of Robert Plant and Alison Krauss' Raising Sand - an approach that's grounded in tradition but has a smoky, smeary veneer that's thoroughly modern…

For Delta Crossroads, Robert Lockwood Jr., a former student of Robert Johnson, returns to his Delta blues roots. This 16-track album features Lockwood with only his 12-string acoustic guitar. It is rather strange hearing old Delta blues sung by one of its originals on a modern recording. All of the notes from the guitar are clear. Plus, his voice isn't scuffed up by the scratches and pop of the vinyl recording. Lockwood plays a mix of Robert Johnson tunes, a few of his own, and some blues standards including "C.C. Rider." With its high production quality and Lockwood's unique and possibly near-extinct style of singing, Delta Crossroads is a strong testament to the endurance of a Delta blues original.

This has been around as a bootleg for some time, a great radio broadcast from February 1972 featuring mainly Bonnie with Freebo on bass but also T. J. Tindle on lead guitar and John Davis playing harp on a couple of tracks. The sound quality isn't perfect but it's pretty good and it captures Bonnie doing material from her first two albums as well as some songs that have never been officially released - Steve Winwood's 'Can't Find My Way Home', John Hurt's 'Richland Woman Blues' and her own song 'Blender Blues'. Although Bonnie sounds young (she was only 22) she also sounds very confident and relaxed, her voice is perfectly controlled and her guitar playing is particularly good on blues like Robert Johnson's 'Walking blues' and 'Richland Woman Blues'.

Chicago-based guitarist Melvin Taylor is a star in Europe, but it may take some time for U.S. audiences to catch on to just how phenomenally talented a bluesman he is. Part of the problem for Taylor may be his own natural eclecticism. He's equally adept playing jazz or blues, but in the last few years, he's forged a name for himself as a blues guitarist with a slew of releases for Evidence Music. Taylor may well be the most talented new guitarist to come along since Stevie Ray Vaughan.

Some people have commented that Tinariwen have always been a country band, albeit a North African take on that most North American of genres. That idea is magnified on new album Amatssou, which finds the Tuareg band’s trademark snaking guitar lines and hypnotic rhythms blending seamlessly with pedal steel, piano and strings from guest musicians including Daniel Lanois, the embellished arrangements lending the songs an epic, universal application.

John Mayall, the pioneering octogenarian British bluesman, has been on a late-career tear. Last year's A Special Life received wide approval from fans and critics alike, while its supporting tour found him playing well-attended shows. Find a Way to Care, his second date for Forty Below Records, is again produced by Eric Corne and features the same band that's been with Mayall for years: guitarist Rocky Athas, bassist Greg Rzab, and drummer Jay Davenport. A horn section also augments select tracks. The material, as usual, is divided between originals and covers. This is a Mayall album that - uncharacteristically - focuses on his keyboard skills: he manhandles B-3, Wurlitzer, piano, and clavinet (and also plays harmonica and some guitar)…

This 19-track compilation focuses on Elmore James' crucial sessions recorded for the Modern Records subsidiaries Meteor and Flair between 1952 and 1956. At the time of these recordings, the distorted amplified sound of James' slide guitar with his unmistakable electrified Robert Johnson lick was helping map out the postwar blues idiom with such classics as "I Believe," "Blues Before Sunrise," "Wild About You," "Mean & Evil," and the extraordinary reworking of Robert Johnson's "Dust My Broom" into "Dust My Blues." Even though roughly half of these tracks appear on the equally recommended 1986 Ace release Let's Cut It: The Very Best of Elmore James, this set is a great introduction to the dynamic slide guitarist's earliest recordings.

"Rambler's Blues," the shuffling hip-shaker that opens Charlie Musselwhite's The Well, is the most autobiographical statement he's ever made – until you listen to the rest of the record. Despite his large catalogue, this is his first record of all original material. Musselwhite's back with Alligator after a sojourn of 14 years, during which he recorded some stellar material for various labels, including the stellar Delta Hardware for Real World in 2006. Musselwhite is accompanied here by a stellar band: guitarist Dave Gonzales, bassist John Bazz, and drummer Stephen Hodges. His own harmonica playing and vocals are everywhere and top-notch. The most compelling thing about The Well is its lack of pretension; Musselwhite has risen to the task of recording a completely autobiographical album that refuses easy cliches, or resting on laurels; its energy is infectious.

King traveled to Nashville in the early 1980s and recorded overproduced pop ballads written by the likes of honky tonk angels Conway Twitty, Willie Nelson, and Mickey Newbury. King plays guitar about as often as Perry Como and Tom Jones would have.
