Heart's 'Barracuda' looks to take a bite out of Motley Crue's 'Kickstart My Heart' in the West Coast regional final of our fan-voted March Riff Madness competition.

Two weeks ago, we started with 32 of rock’s most iconic riffs. Now, that field has been whittled down to eight. We’ll keep going until we theoretically arrive at the most awesome riff in all of rock history.

Heart is without a doubt the surprise of this competition so far, taking out two of the most popular bands and riffs of all time -- Van Halen's 'Unchained' and Guns N' Roses' 'Welcome to the Jungle' -- with relative ease. Motley Crue, meanwhile, beat out a pair of their famous California neighbors, the Doobie Brothers and Metallica, to earn their spot in round three.

So will the pride of Seattle or the Saints of Los Angeles represent the West Coast bracket in our Final Four? You can vote once per hour until the quarterfinals of March Riff Madness closes on Sunday, March 23 at 11:59PM ET. The ultimate March Riff Madness winner will be revealed on Tuesday, April 7.
