Tenor saxophonist Ivo Perelman has been issuing albums at a furious rate recently. Over the last three years he recorded no less than 15 new albums. Like John Coltrane, Perelman's albums are continually questioning the musical orthodoxy and looking for new parts of the musical map to explore. To record "Enigma" he needed to create denser music. That's why apart from his musical blood-brother Matthew Shipp he invites two drummers &emdash; Whit Dickey and Gerald Cleaver. Ivo Perelman boldly goes where no tenor player has gone before.
