Two years after the demise of Return To Forever, virtuoso fusioneers Chick Corea and Al Di Meola are joined on stage by legendary drummer Tony Williams and fretless bass wunderkind Bunny Brunel. The set, mainly of Corea compositions, also features All Blues, a tribute to his former employer Miles Davis. The band is tight, the solos are state-of-the-art and the Live Under The Sky crowd are very enthusiastic. Performed at the Den-en Coliseum, Tokyo on the 27th July 1979 and originally broadcast by NHK-FM.

Bunny Brunel is best-known as a virtuosic electric bassist who is featured in high-quality fusion settings. This particular recording is quite a bit different for Brunel is heard exclusively on acoustic bass, performing advanced jazz standards including pieces by Wayne Shorter, Steve Swallow, and Herbie Hancock along with two of the bassist's originals, "Stella by Starlight," Charlie Parker's "Relaxin' at Camarillo," and "Someday My Prince Will Come." Guitarist Mike Stern has plenty of solos, pianist Billy Childs gets in his spots, and drummer Vinnie Colaiuta is fine in support, but Brunel clearly controls the music. On the concluding "Twelve Bars for Leberstraum," Chick Corea guests on piano.
