Led Zeppelin vs. Black Sabbath – Ultimate Classic Rock Hall of Fame Semifinals

In what could be the heaviest battle in our history, Black Sabbath and Led Zeppelin meet in the semifinals of the Ultimate Classic Rock Hall of Fame election.

Both of these legendary bands breezed through their first round matches. Black Sabbath took 80 percent of the vote against Joe Cocker. And if that wasn't one-sided enough, it was nothing compared to the 86-14 percent drubbing that Led Zeppelin gave to Yes, who probably deserved a better fate than that, but such is the luck of the draw.

Only one of these two legendary groups can be declared the winner and go on to the finals, where they will face either Rod Stewart or Santana. You can vote in that contest here.
