Celebration, a trio from Baltimore, marries sultry and spacey vocals to subdued rhythms, flowering guitars, and bright organ melodies. Their songs range from wide-eyed paeans like "Evergreen" to the more carnal rites of "Pony." Kill Me Tomorrow is the opposite—a trio whose brooding, paranoid art rock is street-dirty and racked by guitar twitches, broken drums, and menacing bass. With Seattle's Dead Science.
