Led Zeppelin legend John Bonham goes up against Alex Van Halen of Van Halen in round two of Ultimate Classic Rock's March Drum Madness.

We placed 32 of the most famous drummers in classic rock history into our March Drum Madness bracket. We're down to the "Sweet 16" already, and that number will be cut in half four more times until we arrive at your choice for the greatest rock drummer of all time.

Bonham's work on tracks like "When the Levee Breaks," "Whole Lotta Love" and his trademark solo showcase "Moby Dick" helped Led Zeppelin become one of the most acclaimed hard rock bands of all time, and it was his untimely death that ended the legendary group forever. He defeated Def Leppard drummer Rick Allen in the first round by more than a four to one margin.

Alex Van Halen, who bested Jimi Hendrix drummer Mitch Mitchell in his first March Madness battle, may not get the headlines his guitar wizard brother Eddie does, but it's hard to imagine their namesake band sounding as magical without his work on classics such as "Hot for Teacher" and "Everybody Wants Some!!"

You can vote once per hour in each of our eight current March Drum Madness battles until the second round closes on March 26 at 11:59PM ET. The ultimate winner will be revealed on April 7.
