"Let's start a revolution," Alan Sparhawk fittingly declares in the almost-title track to Retribution Gospel Choir's new EP, which was issued today as a free download on the band's website. The idea of giving away music isn't exactly revolutionary in this day and age, nor is it all that radical to hear Sparhawk crank it up and rock out with RGC anymore. Still, the four-song collection comes as quite a jolt.

Centered around the riotous Queen-meets-At-the-Drive-in song "The Stone (Revolution!)," "The Revolution EP" arrives just a week and a half after the band came down from Duluth to debut these songs to Twin Cities fans at the Turf Club. And it closely follows a year in which Sparhawk rededicated himself to his original, far quieter trio, Low, whose "C'mon" album brought the band back to the top tiers of indie-rock.

"The Revolution EP" serves as a solid reminder that RGC isn't going away, and it appears to only be getting louder, wilder and freakier. It's definitely worth the easy emailing-list signup to obtain. Local fans will have the chance to hear the songs played live again on April 7 when the band plays First Ave with Caroline Smith & the Good Night Sleeps.
