This actually deserves a thread, I think. Seventy-one twenty song episodes so far. Good bands too. A nice mix of the established bands and some of the more underground ones. Some norsecore and CoF, but that's easily skipped. It doesn't seem to have the most underground bands, but certainly quite a few obscure ones. It's worth a look.
