NotesTAP: THE BOOK OF ANGELS, VOL. 20 is the first collaboration between Pat Metheny and John Zorn, widely considered among their generation's most innovative musicians. Over the past eight years, the songs from the second volume of Zorn's Masada Book have been recorded as volumes of THE BOOK OF ANGELS by a stellar group of musicians. TAP represents Metheny's contribution to this massive project, recorded in his home studio with drummer and frequent collaborator Antonio Sanchez. Says Zorn says of Metheny's recording: "TAP is a showcase for Pat's remarkable imagination, technique, passion, and love for the world."
