I recently stumbled onto "The Black Angels". I was kind of put off by the name, because it sounds like something those greasy Emo kids would listen to. But they have a sound I really like. They are heavily influenced by late 1960s psychadelic music, and a couple of their songs are cringe-inducing knock-offs of that music... but for the most part they have this very cool atmospheric groove that is right up my alley.
