By far the largest collection of concert etudes in the known repertoire, Kaikhosru Sorabji’s set of 100 Transcendental Studies, composed between 1940 and 1944, has a total duration of more than eight hours. On five previous discs, the Swedish pianist (and neuroscientist) Fredrik Ullen has introduced the first 83 etudes to a wider audience, the large majority of them appearing on disc for the first time. Now, 15 years after the release of the first volume comes the final installment, a 2-album set with the last 17 studies. In his own liner notes, Ullen describes the experience of learning and recording the collection: ‘From the F sharp minor of Study 1 to the F sharp minor chord concluding Study 100: traversing Sorabji’s Transcendental Studies has been somewhat like joining a comet following a long eccentric orbit through pianistic outer space, and finally returning back to mother earth.’

Franz Liszt and Olivier Messiaen don't usually spring to mind as similar figures, let alone as an expected pairing for an album, since the former was the arch-Romantic virtuoso pianist and tone poet, while the latter was an influential modernist composer and organist. Yet both men were devout Roman Catholic musicians with mystical ideas that found expression in their works. To be sure, this disc by pianist Fredrik Ullén illustrates the differences between them by presenting their solo piano pieces in alternation, so the listener is never lulled by one style or the other but stays attentive throughout the program.
