Much of Mirage À Trois is similar to the debut album, but most notable is "Claire's Song", which would anticipate the future Yellowjackets with its sequencer and rhythmic elements. Ditto "Goin' Home", a slower, reflective tune and a concert favorite. "Nimbus" also predates the more complex compositions the group would create on later albums, expanding beyond the catch-all "fusion" genre.
