Eight Gigs: ROLAND

San Francisco band Roland used to go by Rappers, but when its guitarist Roland Curtis left the band, the name changed. Even better, the new guitarist's name is Lars Savage. Roland plays math rock, but not like Hella or Tera Melos. Roland's all-instrumental songs are much heavier, like progressive rock but with atypical rhythmic structures, stop-start dynamics and general complexity. It's ideal air guitar music, for you competitive air guitarists. But the most exciting part about this show is that it's free, all-ages and on the Warehouse Artist Lofts' rooftop, overlooking downtown Sacramento. Sorry, Roland. 1108 R Street, www.facebook.com/RolandBandSF.
