Rapper T.I. has released a new album, despite completing his prison sentence just one year ago.

The multi-platinum Grammy-winning artist - who is currently on probation for a 2008 federal conviction on illegal weapons charges - has today (07.12.10) brought out his first musical offering since his release from jail.

'No Mercy' is the rapper's seventh studio album and features not only the voice of the star, but also a whole host of collaborations with other notable artists.

Christina Aguilera sings on 'Castle Walls', while Chris Brown features on the album's first track 'Get Back Up', with Eminem, Kanye West and Trey Songz also making guest appearances on the 14-track record.

T.I. recently explained 'All Falls Down' hitmaker Kanye brought a "combustible energy" to the studio when the pair were laying down tracks.

He said: "Well, Kanye, man, he's a phenomenal talent. It goes without saying that it's combustible energy when we're in the studio. I'm excited to present it."
