Rubblebucket’s bucket list is getting shorter.The theatrical avant-pop band this month played for the first time at the South By Southwest festival in Austin, Texas, and in June will debut at Bonnaroo in Manchester, Tenn.Rubblebucket last year checked off the Crystal Bay Casino Crown Room, where it will return for a midweek brouhaha. It plays Wednesday, April 4. Noah andamp; the Megafauna will open the show at 9 p.m.The eight-piece band left its home base of unseasonably hot Chicago last week, hauling a trailer behind its 15-passenger van. Like seeing the Cubs in October, expect the unexpected when Rubblebucket pours into Tahoe. Part of the show includes a Blondie medley.“We’re high-energy indie pop with lots of avant-garde rock sort of feeling,” said lead singer and tenor and baritone saxophonist Annakalmia “Kal” Traver. “We have stage props and outfits and we recently started touring with two robot puppets. We make it a really fun night for the audience. It’s more than music. We want to have people forget about their troubles.”Traver and trumpeter-bandleader Alex Toth formerly played with the reggae group John Brown’s Body, with which they appeared at MontBleu in 2009. They met at music school in Vermont and joined JBB after graduation in 2006.Also in the band: Adam Dotson, background vocals, trombone; Darby Wolf, Hammond B3, moog, clavinet; Craig Myers, n’goni, woodblocks, percussion; Ian Hersey, guitar, background vocals; Dave Cole, drums; and Jordan Books, bass.b hit the national spotlight last year after releasing its second record, “Omega La La.” A DVD featuring its live show comes out in April.While folks are playing beach volleyball in Chicago, Traver plans to ski for the first time this winter when Rubblebucket plays Tahoe. We just wonder how the giant dancing puppet robots will get on a chairlift.
