Codeine

The early-'90s New York trio Codeine is one of the founders of the slowcore scene that includes groups like Bedhead, American Analog Set, and Low. Taking audible inspiration from the third Velvet Underground album and scene pioneers Galaxie 500, but adding a more aggressive tone and slowing the tempos down even further, Codeine sounded almost entirely unique at the time. However, their style was immediately adopted by a number of other new bands, some of which do the tense and glacial thing even better.
