More prolific in death than he was during his lifetime, rapper Tupac Shakur will be heard anew on yet another posthumous album, "Pac's Life." Due Nov. 21 via Amaru/Interscope, the album sports contributions from superstars such as Snoop Dogg, Ludacris and T.I. on Shakur music that, with the exception of one verse, is all previously unreleased.

Bone-Thugs-N-Harmony guest on "Untouchable," which was produced by Swizz Beatz. T.I. is heard on the title track, a video for which has also been shot. The album also features guest turns from Keyshia Cole, Ashanti, Young Buck, Lil Scrappy, Carl Thomas, Papoose and Big Syke. Production was supplied by LT Hutton, QD3, Ivan and Carvin and Sha Money XL.

"Pac's Life" is the eighth album of Shakur music released since his 1996 murder. "I say it every time, that Tupac left us the blueprints to follow, and without the amazing contributions made by everyone of these artists, producers, musicians, everyone, I do not know how I would get this great task accomplished," says his mother, Afeni Shakur.

The most recent "new" Shakur album, 2004's "Loyal to the Game," featured a host of tracks produced by Eminem. It has sold 1.14 million copies in the United States, according to Nielsen SoundScan.
