by Scott YanowIn addition to a few group originals, vibraphonist Mike Mainieri performs some unusual pieces with his quartet (Joe Lovano on tenor, soprano, and alto clarinet; bassist Eddie Gomez; and drummer Peter Erskine) on this CD, including two folk songs and selections by Leonard Bernstein ("Somewhere"), Frank Zappa ("King Kong"), Aaron Copland ("Piano Sonata"), Roger Sessions ("Piano Sonata No. 1"), and Samuel Barber ("Overture to the School for Scandal"). The pianoless quartet (which displays a lot of versatility by Joe Lovano) turns all of the music into creative jazz. The most interesting aspect to this thought-provoking disc is how difficult it is to tell which compositions are taken from classical music and which are new. There is a surprising unity to the potentially difficult material; the performances on the rather moody outing reward repeated listenings.
