Since their debut in 2001, Sacramento's Hella has excelled at monstrously tight spazz--a none-more-prog take on hardcore with time signatures that shift within measures and dizzyingly complex guitar tablature keeping pace. For years Hella perfected the brew as a duo, but for THERE'S NO 666 IN OUTER SPACE, guitarist Spencer Seim and drummer Zach Hill recruited second guitarist Josh Hill, bassist Carson McWhirter, and--gasp--vocalist Aaron Ross to fill out the band's trademark clatter.
