The Pat Metheny Group released "The Way Up" in January of this year. TWU (as it is now known) is a 68-minute long unified composition - a single piece of music.
Those of you familiar with the Pat Metheny Group will know that the group has always explored long-form compositions (back in the late 70's when they first started out, they regularly stretched earlier songs in live performances to 15+ minutes). Along the way, the group has released a number of long-form compositions, and several albums (including "As Falls Wichita, So Falls Wichita Falls") that could be called suites.
TWU is a truly integrated piece of music derived from a few basic melodic motifs. The above article from motu.com explains how Bob Rice came to work with Lyle Mays on the assembly of the complex collection of musical parts that comprises the finished, mixed version of TWU. There are also some interesting explanations from Lyle himself on the process that he and Pat Metheny followed to write, record and assemble TWU. Lyle is adamant that TWU is not a suite; he explains that it was conceived and written as a single unified piece of music.
By the way, TWU is pretty damn good live also...I saw the piece performed pretty much in its entirety (except for the play-out section) here in Dallas in March by PMG (newly augmented by the excellent Nando Lauria). More of that concert at a later date.
