This semifinal round of the 100 percent fan-voted Ultimate Classic Rock Hall of Fame matches two bands that took very different paths to classic rock glory. It’s the Band against Jethro Tull.

In the first round, the Band grounded and stripped the pilot’s license from Jefferson Airplane with more than 83 percent of the vote. Meanwhile, their opponents Jethro Tull had a comparatively tougher time in their battle against the Allman Brothers Band, but still cruised to a comfortable 65-35 percent victory.

From their days in Canada as the Hawks to Bob Dylan’s backup band to the hit records under their own name, the Band have always been proponents of the less-is-more approach, using their talents sparingly to let the song breathe. Jethro Tull, on the other hand, found stardom on the strength of concept albums and extended compositions that displayed their instrumental virtuosity.

And even though both groups had auteurs (in the Band's Robbie Robertson and Tull's Ian Anderson), the Band relied on a trio of excellent singers — Levon Helm, Rick Danko and Richard Manuel -- while Tull’s vocals were handled exclusively by their leader Anderson.

If the two groups had anything in common, it was that they both came from a strong background in folk music and made innovative use of keyboards.

But which one will move on to the finals? That's your call. You can vote once per hour until 11:59PM ET on Feb. 23. This month’s winner will be announced on March 3. Be sure to read our official rules.
