The Davis High School Jazz Band, under the direction of Fred Lange, will join the line-up of entertainment at the fifth annual Davis Jazz Festival hosted by the John Natsoulas Center for the Arts on Saturday. Pictured during a performance last spring at the Monterey Next Generation Jazz Festival are, from left, saxophonists Jenny Horn, Richard Chew and Scott Yamamoto and trombonist Alejandro Lavernia. The band will perform from 4:15 to 5 p.m. at the main stage at Davis Commons, First and E streets in downtown Davis. The Band Boosters will host a raffle during the performance to raise funds to support the band program. Grand prizes include a Visio tablet computer and a weekend getaway at a Tahoe cabin.
