by Scott YanowThis Return to Forever set finds guitarist Al DiMeola debuting with the pacesetting fusion quartet, an influential unit that also featured keyboardist Chick Corea, electric bassist Stanley Clarke and drummer Lenny White. On this high energy set, short interludes separate the main pieces:"Vulcan Worlds,""The Shadow of Lo,""Beyond the Seventh Galaxy,""Earth Juice" and the lengthy"Song to the Pharoah Kings." Acoustic purists are advised to avoid this music, but listeners who grew up on rock and wish to explore jazz will find this stimulating music quite accessible.
