Backstage at last year’s Lollapalooza, amidst the likes of LiLo, Joe Perry and Lou Reed, the celebrity sighting that really sent the kids all aflutter was that of Jack Black’s lesser known but equally hilarious Tenacious D sidekick Kyle Gass. Gass has birthed a chicken fried steak-flavored hybrid of Skynard and Spinal Tap with his latest band, Trainwreck. Songs like “Milk the Cobra” and “Brodeo” (sporting the lyric “we’ve got Jan Claude Van Damme as our BroOverlord”) showcase KG’s stellar sense of humor, the kind which can only be fostered going through high school with Gass as your last name.
