Bart McCrorey is probably best known for his skate-punk outfit Frontside Five. Throttlebomb (due Saturday, March 2, at the hi-dive) isn't a quantum leap from that, but it's more a synthesis of speed metal and glam. It's a bit like Motörhead, but with more of a focus on melody: A backbone of boogie and blues rock informs the songwriting, which is nonetheless splintery and aggressive. With Low Gravity's Adam Mullins on drums and Jenn Rad, formerly of the Blackouts, on bass, there's a solid groove that gives McCrorey and guitarist Justin Delz a foundation from which to indulge in tasty guitar solos. Throttlebomb will release its debut album at this show, which should recall the glory days of the 15th St. Tavern, where hard rock and punk were always on tap.
