My friend Beth is one proud mama. Her daughter’s band, Mariachi Flor de Toloache, is set to play The Late Show with Stephen Colbert this coming Friday, September 25.

In case your vision of mariachi is limited to portly gentlemen in tight-fitting suits, take a look at Flor de Toloache, the only all-women mariachi in New York City:

OK, the tight-fitting suits part was correct.

Flush with the glory of their recent Mexico tour–the only all-female US mariachi group ever to do so–Flor de Toloache has thrown themselves into their new project, playing both warmup AND backup for The Arcs, the new band formed by Black Keys’ Dan Auerbach.

What’s funny is, Mr. Auerbach had no idea he was about to change his whole band’s sound when he asked his manager to hire a mariachi band. Beth says no one told him the band was all-women–not to mention all-gorgeous. Even funnier, he hired them to play. Only after realizing he dug their instrumentals did he happen to ask, “You guys don’t happen to sing, do you?”

Do they!

So now The Arcs are scheduled to play for Mr. Colbert and his shiny new Late Show next Friday, and guess who will be featured? I’m not really a Late Show person (though I do love Stephen). I’m not really a mariachi person either. But these women are DYNAMITE, so not only will I be watching them and cheering them on, I hope a whole bunch of you guys tune in too!

Then tell me what you think, eh? Ai-ai-ai-ai-ai!!!!
