When No Age started in the middle of the last decade, their releases came as if from a flood. In their first three years as a band, the Los Angeles duo of drummer Dean Spunt and guitarist Randy Randall issued a string of a half-dozen singles, a compilation that collected many of them and a full-length debut on Sub Pop. As tours increased, they slowed a bit, yet they managed another full-length, EP and two singles in 2009 and 2010. And then, mostly silence: Their first album in three years, the new An Object, finds them attempting to rebuild the model of their propulsive indie rock minimalism. Spunt started banging objects besides drums, including a bass and contact microphones, and they began ripping ideas of song structure apart. The result is a curious collection of songs that moves from the slow and wistful to the blustery and distorted, all while refusing to kowtow to expected verse-chorus-verse ideas. It sometimes falters, but it always rushes headlong with new ideas, the point of No Age from the start. With Spider Bags.
