Gravitas Quartet: 21st century chamber jazz

Wayne Horvitz‘s San Fran performance is previewed.

Wayne Horvitz knows that if he still lived in New York, his Gravitas Quartet, which performs at the San Francisco Jazz Festival on Sunday, Nov. 9, might be a bigger deal.

But the pianist/keyboardist/composer moved to Seattle with his wife, Robin Holcomb, 20 years ago, and besides distancing himself from such long-standing musical friends as John Zorn, Marty Ehrlich, Butch Morris and Doug Wieselman, the migration removed Horvitz from the media limelight that shines on Manhattan musicians, even those in the avant-garde Downtown scene of which he was a key player.
