Isley/Jasper/Isley was a splinter group of the Isley Brothers formed in 1984 by brother-in-law Chris Jasper (keyboards), Ernie Isley (lead guitar) and Marvin Isley (bass), due to creative differences that arose among the group.Jasper, a classically-trained musician and composer and the key songwriter, producer and arranger of the Isley Brothers music, became the lead vocalist on most of the trio's recordings, and was also responsible for the majority of the writing and production for the new group. The older Isley Brothers returned to their original vocal trio formation and continued to record, employing a number of musicians, producers and writers to fill the void left by Chris, Ernie, and Marvin.
At this 1974 concert baritonist Gerry Mulligan and trumpeter Chet Baker had one of their very rare reunions; it would be only the second and final time that they recorded together after Mulligan's original quartet broke up in 1953. Oddly enough, a fairly contemporary rhythm section was used (keyboardist Bob James, vibraphonist Dave Samuels, bassist Ron Carter, drummer Harvey Mason, and in one of his first recordings, guitarist John Scofield). However, some of the old magic was still there between the horns, and in addition to two of Mulligan's newer tunes, this set (the first of two volumes) also includes fresh versions of "Line for Lyons" and "My Funny Valentine."
