Trying to figure out what Mouthus sounds like is a popular pastime. The New York duo, often associated with the current noise-drone movement, has stumbled across a novel synthesis, and like any really cool magic trick, critics are trying to decode it. One key element that's rarely mentioned is indie rock -- not the new crap like Arcade Fire, but the classic lo-fi shit: Dinosaur Jr., early Sebadoh, the Grifters. Of course, Mouthus doesn't really sound like any of those bands, but the duo is so a part of the American indie tradition, which basically has its roots in two groups: the Velvet Underground and Neil Young & Crazy Horse. Sullivan and Nelson, you see, are ragged dudes with a love for feedback and jamming (that's what indie rock used to be about). And all those other influences, however exotic, are filtered through this tradition.
