In 1977, jazz was experiencing a rather wanky weather report, and many masters of prognostication predicted heavy fusion to reign. Then came the Rova Saxophone Quartet. Blasting away all notions of tradition, the group featured four saxophones and limitless imagination. Over 30 years later, the group still defies all cliché, stoking the spirit of free jazz but perpetually inspired by fellow pioneers of structure like John Zorn and Terry Riley. There’s no reason for any open mind to miss it when Rova plays on Saturday, Feb. 19, at the Dance Palace. 503 B St., Pt. Reyes Station. $24–$29. 415.663.1075.
