It’s the mark of a fine musician to be able to span decades and remain relevant. While an entire generation of turntable DJs grew up on Herbie Hancock’s “Rockit,” with its industrial beats and extended scratch outro, their parents were vibing out to the visionary pianist’s classic Blue Note albums like Empyrean Isles and Maiden Voyage. (Not to forget the big siblings in the club, dancing to acid-jazz samples of “Chameleon.”) These days, Hancock’s live set is adventurous as ever, evidenced by a version of “Watermelon Man” in 17/8 time. Alternating between piano, synthesizer, vocoder and keytar, the jazz master plays “Plugged In: A Night of Solo Explorations” on Saturday, Sept. 28, at the Green Music Center. 1801 E. Cotati Ave., Rohnert Park. 6pm. $25—$85. 866.955.6040.
