On any given night, there might be 18-25 members of Boston's Bang Camaro onstage during a show, with 15 consistent "lead singers" and a backing band with two lead guitarists, co-founders Alex Necochea and Bryn Bennett. The pair bonded over their love of "really bad music of the '80s," Bennett says, namely pop-centric hair metal like Mötley Crue and Def Leppard.

Bang Camaro believes in two core values—catchy guitar riffs and memorable choruses—which is why it generally does away with superfluous elements like verses and bridges. Onstage, the crew is a haywire all-male choir, with minor pyrotechnics, fist pumps and hand claps and the occasional black eye all figuring into the mix.

Bang Camaro's "electric fire" ignited fans at Harmonix, the videogame manufacturer that recently added such tracks as "Push Push Lady Lightning" to the playlist on "Guitar Hero II" and "Rock Band." The Agency Group has also committed to booking the unsigned act and will launch its national tour starting with a Jan. 31 gig during a New York Titans pro lacrosse game at Madison Square Garden.

While Bang Camaro has an album available for purchase, "we don't think it's necessary to be making full records anymore," Necochea says. " 'Guitar Hero' is the whole reason we can make our way out to L.A. and nearly sell out the Troubadour."
