The fourth opening-round battle of the 2013 Ultimate Classic Rock Bowl features a distinct British flavor, as the Who and the Beatles duke it out in a quest for championship gold. Over the next month, 16 of rock’s biggest bands will square off against each other in a series of single-elimination matches to determine the genre’s true champion.

It's hard to imagine two groups who have had more impact on the history of rock music, specifically on the evolution of the album as an art form. Need proof? Try these titles on for size: 'Revolver.' 'Tommy.' 'Sgt. Pepper's Lonely Heart Club Band.' 'Quadrophenia.' 'Abbey Road.' 'Who's Next.'

So which of these game-changing artists will emerge victorious here, the Who or the Fab Four? It's entirely up to you and your vote, which you can cast below -- as often as every hour if you so choose.

The polls for all eight first round matches close on Sunday, Jan. 13 at 11:59 PM ET. The 2013 Ultimate Classic Rock Bowl winner will be announced Feb. 4 — the day after Super Bowl XLVII.
