Master P, Method Man, More Break Out For "Oz" LP

The hard-hitting HBO prison drama "Oz" has inspired a hard-hitting hip-hop album.

Snoop Dogg, Cypress Hill, Method Man, Master P, Trick Daddy, Kurupt & Nate Dogg, Goodie M.O.B., Jadakiss and Styles of the LOX, Devin The Dude, and Three 6 Mafia have all recorded new music for an "Oz" album to be released January 9 on the EMI-distributed Avatar Records label.

"The hardcore, often violent and controversial themes contained in the show create a perfect forum for some of the most aggressive rappers in the industry," said the label's CEO in a press release announcing the project.

A label spokesperson confirmed that Master P and Method Man will both be making cameo appearances on the weekly series when season four resumes in January with eight new episodes. Other musicians who have appeared in cameo or recurring roles on "Oz" include Treach of Naughty By Nature, Evan Seinfeld of Biohazard, L.L. Cool J, David Johansen, and Sandra "Pepa" Denton.

The album is also doing double duty as a fundraiser for the Innocence Project, which helps to free wrongly accused death row inmates through DNA testing.

The organization, which is headed up by celebrity trial attorney Barry Sheck (who defended O.J. Simpson, among others), will receive a substantial donation and a royalty from album sales, according to the label.

"The artists have all come together for this project as a way to give back, as they all personally know someone in prison," the label spokesperson told MTV News.
