Two very different bands -- grunge heroes Soundgarden and '80s glam-metallers Poison -- vie for your votes in this month's newest Ultimate Classic Rock Hall of Fame battle.

Every month, our readers will decide which of eight legendary artists or bands will be honored for their contributions to the genre. We're guessing most people are going to know which way they're going to vote pretty quickly on this one.

Poison exploded onto the national scene in 1986 with their multi-platinum debut 'Look What the Cat Dragged In,' and went on to enjoy a long run as one of the leaders of the "hair metal" movement. They've toned down the makeup and outrageous outfits quite a bit since that time, but remain a big concert draw.

Although they weren't the first band from the grunge explosion of the early '90s to reach mainstream success, Soundgarden have certainly remained among the most popular and vital. Their 1994 masterpiece 'Superunknown' set a creative high mark for the genre, and after a decade-long breakup the group returned to considerable acclaim with 2012's 'King Animal.'

So who gets to move onto the next round — Poison or Soundgarden? It’s your call. You can vote once a day between now and Monday, Nov. 17, at 11:59PM ET. This month’s winner will be announced on Dec. 2. Be sure to read our official rules.
