Tupac Shakur's former group, the Outlawz, plan to release a new album in honor of the late rapper. The rap quartet, which consists of Young Noble, E.D.I. Mean, Kastro and Hussein Fatal, will drop their final LP 'Perfect Timing' on Sept. 13, which is the 15th anniversary of Tupac's death. According to HipHopDX.com, the collection will boast guest appearances from veteran rhyme-slingers Bun B., Scarface, Tech N9ne, Trae tha Truth, Krayzie Bone and Young Buck.

The Outlawz say that their new album is much needed in the rap game right now. "The industry and the streets are begging for something real so we here to deliver," states Young Noble. "It's time for some real soldiers with a real message making real music with a real history to step to the front of this rap game, and the Outlawz is the epitome of just that ... 'Perfect Timing.'"

Along with the album, the Outlawz also plan to release an accompanying DVD titled 'Outlawz Worldwide, Vol. 2.' But before that, a mixtape called 'Killuminati 2K11,' hosted by DJ Kayslay and DJ Smallz, will drop via the Internet on July 14.

The Outlawz are a rap collective that was founded by Tupac Shakur in 1995. The group is infamously known for their blistering diss song 'Hit 'Em Up,' where they attacked the late Notorious B.I.G. and other east coast rappers. The Outlawz have released four albums altogether, including one featuring 2Pac's posthumous verses called 'Still I Rise,' which went double platinum.
