Jimmy Chamberlin (the Smashing Pumpkins)
Chamberlin stood out so hard in the Smashing Pumpkins that the founder, Billy Corgan, didn’t have faith that he would stick around in the band. He stuck around, in fact, he brought an element that drove the Smashing Pumpkins to the level of fame that they are on today. Chamberlin shined on Melancholy and the Infinite Sadness, but in modern years he has taken a step away from the Smashing Pumpkins to pursue his own endeavors outside of music.
Carter Beauford (the Dave Matthews Band)
DMB should be called the Carter Beauford Band because he completely owns pretty much all of their songs. DMB would be nothing without Beauford, no offense to Dave Matthews, he’s a great songwriter, but DMB without Beauford would have never left the ground. Also, Buford set a Guinness World Record for having the largest touring drum set in music history in the early '90s.
