So here's one of those rare band you find once in a while, Graveyard. When I first heard them at a friend's place, it sounded like some forgotten band from the 70's. But this is actually recorded very recently and it seems the feel from Led Zeppelin & Black Sabbath is very present in the both sound and the notes. Great stuff. Wikipedia link here
Just did a quick shot at this on the guitar:
* It's downtuned to D.
* It's mostly the chords C G A.
* Solo stuff goes in A.
