Adam Patterson is drummer, percussionist and vocalist with The Expendables. Adam started off not playing the drums, but playing bass guitar. Initially he formed a band called Eternal Boner. At that time they band did not have a drummer. Recalls Adam: "So I bought a shitty drum set for 150 bucks and kept it in the garage for the occasionally friend that wanted to try and play with us. Our friend Kevin Lemon wanted to jam with us but he played the bass, not the drums. I was the only one that could sort of keep a beat and Kevin had a much bigger, louder amp so I became the drummer."
