Los Angeles jam band Particle -- who sprinkle their rock-based sound with flecks of funk, electronica and jazz -- will bring their national tour to HumBrews in Arcata on Friday. It's their first extended tour in nearly six years. The band also is working on their first LP since 2004's “Launchpad.” “After forming in 2000, Particle quickly became one of the pioneers of the emerging livetronica scene, and they went on to perform over a thousand concerts in eight different countries,” according to a news release. “They soon became known for staging epic marathon sets at national festivals including Bonnaroo, Coachella, Lollapalooza and Austin City Limits. For their upcoming tours, the band will continue its tradition of combining a full light show and multimedia production with their signature mix...” Particle comprises founding member/keyboardist Steve Molitz, longtime guitarist Ben Combe and newcomers Clay Parnell on bass and Brandon Draper on drums. Although it'll just be the four musicians this time around, Particle shows in recent years have featured artists such as Josh Clark of Tea Leaf Green, Michael Kang of The String Cheese Incident, Dan Lebowitz of Animal Liberation Orchestra, Pete Wall of The Motet and many others. Advance passes for the 21-plus show at the 856 10th St. are $15. The doors will open at 9:30 p.m.
