So you may recognize Kirk Windstein as being the guitarist for stoner metal supergroup Down, who are on tour right now supporting their new record, Down III - Over the Under. However, he is also the frontman of Crowbar, one of probably THE heaviest bands EVER. We met up with Kirk a couple weeks back to talk about the new Down record, and while we were at it, he took the time to show us some fucking BRUTAL Crowbar riffs, as well as his new custom finish ESP guitar. Check out the footage above, and check out part one of the Down interview below.
