The second round of the 2013 Ultimate Classic Rock Bowl features a lot of interesting matchups -- perhaps none more intriguing than the one pitting Van Halen's sunny, California-raised pyrotechnics against the more cerebral music of England's Pink Floyd.

16 of rock’s biggest bands met up earlier this month in a series of single-elimination matches to determine the genre’s true champions; now only eight remain. Van Halen advanced by taking 66% of the vote against fellow L.A. legends Motley Crue, while Pink Floyd surprisingly toppled the reigning kings of hard rock and metal, Metallica, in a 65% to 35% runaway.

So now who moves on? That's up to you.  You can vote once per hour in each of the four second round matches from now until Sunday, Jan. 20 at 11:59 PM ET. The winner of the 2013 Ultimate Classic Rock Bowl will be announced Feb. 4 — the day after the Super Bowl.
