Check out my brother's band, Unmothered. The drummer used to play in The Hidden Hand with Wino, and the vocalist/guitarist used to be in another local Austin band, Lions Of Tsavo. They call their sound "Haunt Rock," but it's also really sludgy. A bit more mid-tempo at times. I'll let you judge for yourself what to call it.

They're currently on tour, I believe they're in New Orleans today and tomorrow.
