Trashy, seedy, campy rock n' roll with an often androgynous, drunk/drugged out, and b-movie-obsessed disposition. Many trash rock bands are punks reviving the feel of the raunchiest '60s garage bands. Surf rock, rockabilly, and raw garage rock are usually prime components.
The Cramps are Gods of trash rock. They are not its only "big name", but no trash rock fan will deny them and they are probably the biggEST trash rock name.
