Red Hot Chili Peppers bassist Flea is known for his diverse playing style, which ranges from melodic to aggressive slap-bass, but he's also a philanthropist.

On Tuesday, the L.A.-based rocker tweeted the details about an upcoming EP, "Helen Burns," the proceeds from which will benefit the Silverlake Conservatory of Music, a a non-profit music education organization that Flea co-founded in 2001.

According to Flea, whose real name is Michael Peter Balzary, the EP is of "obscure, arty mostly instrumental music" and features guest vocals by punk-rock legend Patti Smith. The EP will be released in digital, pay-what-you-wish format, and as an autographed $75 collectors' edition vinyl.

"Helen Burns" was recorded after the Red Hot Chili Peppers 2006-2007 tour for their album "Stadium Arcadium."

"It is not [Red Hot Chili Peppers] music or even close to it," Flea tweeted. "It is a trippy freakout."

Details on ordering will be released in the next few days.
