The two albums I listened to constantly at 13:
Mighty Mighty Bosstones - Let's Face It
MxPx - The Ever Passing Moment
Mike Herrera from MxPx inspired me to play bass, and the first rock show I ever saw was the Bosstones. Cool/interesting tidbit about that show: one of the opening bands was Simple Plan, who was completely and utterly unknown at the time. I'm not exaggerating when I say that the theater was basically silent when they were introduced. Then their debut album came out two weeks later, and they exploded.
