Music to protest by

Free live music is plentiful in the Twin Cities during the RNC -- and much of it with a political flavor. Yesterday's Ripple Effect concert at the Capitol featured the Orthodox Jewish reggae artist Matisyahu, local female hip hop artist Indigo and Michael Franti.

The SEIU Labor Day Festival on Harriet Island showcased some big name acts including Mos Def, Billy Bragg, Steve Earle and local hip hop stars Atmosphere.

As part of their Electorate Fetus event, the Electric Fetus is hosting a series of free performances by local artists, including Chris Koza and Romantica.

The marches over the last two days have also featured their own musical accompaniment. Songs overheard by MPR reporters at the events:

"Paper Planes" - M.I.A.
"Holiday in Cambodia" - The Dead Kennedys
"Guarantees" - Atmosphere
"Bulls on Parade" - Rage Against the Machine
A dance remix of Madonna's "Like a Virgin"

And, of course, crowd renditions of "We Shall Overcome" and "Give Peace a Chance."

What songs did you hear at the marches? And what other free music are you planning to check out this week?

The Provention show last night was awesome at the Fitz w/ local musicians.
