There's quite a lot. Testify, War Within A Breath and Born Of A Broken Man are in Drop D. There are probably more but that's all I can remember off the top of my head.

Alright, I'll give them a try, Japanese Black Speed rarely disappoints.

Hmm judging from your pic you'd fit in more with a fat busted tribute.
Testify, Born Of A Broken Man, War Within a Breath, No Shelter. I think there are one or two more, but I'm not sure which ones.
