The holiday season is upon us, and we hope you'll take time out from your schedule of shopping and ugly sweater parties to vote for either the Moody Blues or the Beach Boys in the semifinals of the 100 percent fan-voted Ultimate Classic Rock Hall of Fame.

Every month, our readers will decide which of eight legendary artists or bands will be honored for their contributions to the genre. In the first round, the Beach Boys comfortably defeated Bob Dylan, taking almost 58 percent of the vote. The Moody Blues, for their part, steamrolled past the Who by a three-to-one margin.

While both bands got their start in the '60s and have continued working through today, they are more commonly associated with different eras. The Beach Boys' "classic period" is usually defined as their early, sun-drenched singles that led up to the far left turn of their 1966 masterpiece 'Pet Sounds.' For the Moodies, 1967's 'Days of Future Passed' kicked off their 20-year string of hit albums that blended rock, pop and classical music.

But only one of these bands can make it to the finals, and that's where you come in. You can vote once an hour between now and Monday, Dec. 22 at 11:59PM ET. This month’s winner will be announced on Dec. 30. Be sure to read our official rules.
