Death From Above 1979!!!
I know people usually talk about basses here, but I felt it was appropriate to mention them as this band consists of two people. A bass player and a drummer.
My band played with them last night and I have to say that they are one of the best live acts I've ever seen. Probably the loudest, too. Their bass player was playing this lovely old Rick and running about 1300watts of tube power.
Anyway, if you haven't heard them, I strongly suggest you check it out. They're doing something completely unique, raunchy, fast, yet completely fun. It's amazing what you can do with a bass.
