An obscure recording that finds Coryell in solo, duo and group settings. The group performances range from free ("Octaves") to funk ("Memphis Underground"). Of the two solo guitar performances, "Improvisation," is the more cohesive as "Acoustic Solo" finds Coryell laboring for speed, a fault that has often hindered his playing. "Picean Moon" is a moody piece similar to the "ECM sound," with Michael Brecker sounding like a dead ringer for Jan Garbarek. "Serabond" is a fine acoustic duet with Steve Khan and even includes a quote from "Theme from Love Story." Despite some interesting moments, Difference is too inconsistent to sustain a lasting interest.
