Chick Corea was involved in a wide variety of projects during the early 1980s, some acoustic, others electric, and everything from solos and duets to orchestral projects. Touchstone really displays quite a bit of diversity with features for flamenco guitarist Paco DeLucia, a one-song (“Compadres”) reunion of Return to Forever (with guitarist Al DiMeola, bassist Stanley Clarke, and drummer Lenny White), a spot for alto-great Lee Konitz (“Duende”), and a conventional sextet outing on “Dance of Chance.” A bit uneven but with its interesting moments, Touchstone is worth checking out. – Scott Yanow
