Thurston Moore, guitarist and vocalist with Sonic Youth, has started his own online record label offering MP3s and stencils. And it's all free.
As Mr Moore says ...'WWW.PROTEST-RECORDS.COM exists for musicians, poets and artists to express LOVE + LIBERTY in the face of greed, sexism, racism, hate-crime and war. FIGHT THE GOOD FIGHT. All songs and designs on this site are free to share, not to sell.'
You can find tracks by the Beastie Boys and Cat Power up there right now amongst others.
Go to Protest Records and spread the word.
