Song from Season 2, Ep. 2 (the one with Slayer)

Hi
I was wondering if anyone knows the song from the episode when Slayer comes to play at the house. Its the song that's playing in the background when Bam and Dunn are riding quads around, "landscaping." Any help is appreciated. Thanks.

yeah the song is this darkened heart by all that remains...i kno its my second fave band...lol there good live

do you know the name of the song when Dunn screws up the bone? it s a quick guitar riff but its awesome
