Query: Sludge

This band is horrid, one of the most over rated over the currently over hyped Indie scene. I saw their concert for Directions to See a Ghost and wish I hadn't. If this is "psychedelic rock" it's a one hell of a bad trip. Velvet Underground, Iron Butterfly, The Doors, The Airplane, none of them were this dim, dreary, and lumbering. The only good thing about seeing them live was being introduced to The Warlocks, a much better band who aren't a bunch of pseudo-60s posers. Try them instead. Black Angels suck.
