Flashback - Heart

It's time to go back in time again, kids - FLASHBACK!  What makes a track heavy metal?  Galloping guitar riffs?  Shrieking vocals?  Angry lyrics?  In 1977, Heart released its third album, Little Queen, and the album was promoted on the strength of the single "Barracuda."  Reportedly written by Ann Wilson in a fury after being asked by a record promoter where her lover was (in reference to Nancy Wilson - her sister), the track meets the requirements of the blog - CRANK IT!

P.S.:  Check out Roger Fisher's leather vambrace - what's more metal than that?  Well... I guess... I guess a metal vambrace, but you know what I mean - RAWK!
