Cheyenne Saloon, June 2

Charlie, Bipolar’s mono-named lead vocalist, knocked me out with her one-two punch of guttural screaming rage and melodic vocals. Rounded out by bassist Chris Kmit, who’s head seemed to be on a permanent swivel with some major windmills, Bipolar is one badass four-piece. This local band—who formed in Sacramento, Calif., in 2003 and relocated to Vegas in 2008—offered a powerful blend of alternative and melodic metal, sounding somewhere between Deftones and Glassjaw. Bipolar has slowly but surely cultivated their craft, and it shows in the newer songs, which have hooks that grab on and hold tight.

Dressed in ’70s-style purple shorts, along with tube socks and a pair of green Chucks, Charlie rocked out their song, “Pigs.” She followed with a cover of “Bloodline” by Slayer, to which she added her own unique spin. How many of us have ever heard a female singer cover Slayer and pull it off? Charlie did.

Bipolar will be entering the studio to record new songs next month, and combined with a new video, it looks like they will be the new heavyweight contenders. ★★★☆☆
