On their MySpace, Horse The Band characterizes themselves as "melodramatic pop song." OK.
I would put them somewhere between hardcore, noise, and obnoxious noise-rock because they sound like they're playing all three all at once. At times, the vocals attempt to be melodic, which is confusing and probably the point.
The band members are ugly, the music is loud and abrasive, and I haven't seen a music video this good in, um, years. Everything here works...
When I find the whole album, I'll get a full, more descriptive review up. Maybe I'll include something to download too. In the meantime, check them out here.
