Ten-piece L.A. band Ozomatli have been bringing their unique stew of hip-hop, salsa, funk, and reggae sounds to awestruck audiences for more than ten years. I was lucky enough to catch them on their first major US tour in 1998, and I've been a diehard fan ever since. When I tell you that their concerts are a hip-shaking, fist-pumping, mind-altering experience, it's not an exaggeration. Blasting horns, percussion breaks, ukulele solos, dancing MCs, and a drum circle only scratch the surface of the things you'll get at this non-stop party.

More than just a party, though, Ozomatli have a message in their mayhem. They inject a healthy amount of political themes in their addictive hooks and rump-shaking beats. I must admit that it was rather shocking to see them on Dancing with the Stars recently, but I suppose in this age of declining record sales and disappearing record labels, you have to do what you can to get your name out there.

It's nice to see the band adding an extra show outside of Boston this tour, so by all means, get up to the Music Hall in Portsmouth, N.H., if you can this Sunday, May 11. It all starts at 8 p.m., with tickets going for $30 and $26. By the way, there's also the regular live date at the Paradise in Boston (more room there for dancing, actually) on Saturday, May 10, at 8 p.m.
