Gang of Four — the Leeds, England-based rock legends — are open for business with a new album.

Content is the band's first new material in 16 years. The band has a sound of its own invention, featuring leftist lyrics set to a punky, funky, serious groove you can actually dance to. And not just slam dancing either!

Gang of Four is often considered a leader of the late 1970s/early 1980s post-punk movement, and they remain highly influential. Just ask Michael Stipe of R.E.M., or Flea from the Red Hot Chili Peppers. You can hear the band's influence today on a whole new generation of indie-rock bands from Franz Ferdinand to Bloc Party, Clinic and the Rapture.

The "fan-funded" Content is still everything you'd want from Gang of Four. Jon King's jittery vocals battle it out with Andy Gill's rap, alongside his jagged guitar riffs. The group's new rhythm section keeps it funky and danceable.

King and Gill are into their '50s and haven't lost a step musically. Check out the urgency on "You'll Never Pay For the Farm," which might be about the banking crisis. They may have softened their leftist stance a bit, but there are still plenty of wrongs to right. Gang of Four touches on topics like the evils of the Internet, and the debt crisis. The band takes on everything but the kitchen sink on one of the album highlights, "Who Am I." King sings, "Who can lie when everything is true?/Who wants old when everything is new?/Who am I when everything is me?"

It's not all about the urgency. One of the album's more interesting tracks, "Fruitfly In the Beehive," shows a more easy-going vibe, but still contains powerful words. "And when the true believers die/more and more get born again/If the queen can't cope at all there's a number she can call."

Three decades in, Gang of Four are still delivering the goods. Music with a message that you makes you wanna shake your groove thing! Keep on keeping on, guys!
