Girl in a Coma performs at the Double Door in Chicago in April 2010.

Don’t believe me? Go check out Girl in a Coma when they drop by St. Louis for a show at the Firebird September 5, and you may change your tune (pun intended).

The group, based in San Antonio, is currently signed with Joan Jett’s Blackheart Record label and derives their name from the popular Smiths’ song “Girl in a Coma,” a fun fact that alternative junkies will most likely notice.

Style-wise, they’re hard to pigeonhole. But, just as convergence journalism is fast becoming the ideal for the news industry, the ability to combine several genres, and combine them well, is a golden ability and an agent’s dream.

And you better believe these girls deliver.

Nina Diaz’s (lead vocals/guitar) vocal method is reminiscent of old style jazz, a quality rarely seen in today’s music world. At the same time, she appears to be pulled out of the ’80s without seeming dated. Her sister Phanie (percussion) keeps the beat with punchy and consistent drumming and Jenn Alva (bass/second vocals) adds pleasant vocal harmonies.

Be sure to listen for “Clumsy Sky,” as Nina handles the dreamlike introduction in such a way that you’ll be swept up in the song. Their new album, “Static Mind” is an assertive alt-rock ditty with a melody that, personally, I can’t get out of my head. And I dare you not to sway when you hear the slow, vocal driven “El Monte.”

The show starts at 8 p.m., and tickets will run about $10 to $12.
