Tenacious D is pretty awesome. I got a chance to see them perform a couple of songs when they opened for Queens of the Stone Age at a benefit concert. Which thus brings me to my favorite rock band: Queens of the Stone Age. Josh Homme is a god damn genius.
Bullet for my Valentine is absolutely my favourite band, because I love those vocals, the guitarsolos and so on! Rise Against has also great textes, but I don't like the guitarsolos as much as those of BfmV.
