There's been a lot of buzz around Charles Manson this past month.

Last Friday (3/17) an ABC documentary about Manson aired focusing heavily on his dream of securing a recording contract. He worked with Neil Young and even Brian Wilson of The Beach Boys, but despite his connections with such esteemed musicians, Manson wasn't taken seriously by record producers.

Most of his music has existed in bootleg form and now a tape he made while at San Quentin prison in the 1980s is available as a limited vinyl package.

According to Billboard: Walking in the Truth cleans up the rough sonics of the cassette release, says Danbury, Connecticut-based musician and record collector Malcolm Tent, who produced and pressed the LP.

"I wanted to make a tasteful package," Tent tells Billboard. "With me, there's a huge fascination with uncovering these lost nuggets, especially from what's come to be known as 'outsider artists.' I think Charles Manson is probably the ultimate outsider: He is nowhere near our society or our reality."

Manson, 82, is currently serving life sentences for leading and directing multiple killings that took place in the summer of 1969.

Charles Manson cannot legally profit from these recordings, all proceeds from the release will go to environmental charity Air Trees Water Animals, which is run by a close friend of Manson.
