Zakk was on the local radio station yesterday and played a couple of acoustic tunes. He did an absolute killer version of Suicide Messiah and a song called In the River which he did as a tribute to Dimebag Darrell
You have to check out Suicide though... one man, one guitar and a wall of sound.
Also, if you scroll down a bit, you'll see some other killer acoustic stuff he did from May 2003.
Just thought I'd pass it along...
