Bun B's new solo album, 'Trill O.G.: The Epilogue,' hits stores today, and Spotify is giving fans a full stream of the project.

The album, which is the fourth and final installment in the Port Arthur, Texas rapper's 'Trill' series, packs in plenty of collaborations across 14 tracks. Rick Ross, 2 Chainz, Raekwon, Big K.R.I.T., Devin The Dude, Royce Da 5'9", Kirko Bangz, Trae Tha Truth, Z-Ro and Bun's late UGK partner Pimp C (by way of previously recorded vocals) all make appearances.

'Trill O.G.: 'The Epilogue' is a compilation of the best leftover material that didn't make his 2010 LP, 'Trill OG,' Bun told Rap Radar last month. The release of this new effort marks the return of the storied southern rap label, Rap-A-Lot Records -- the company secured a distribution deal with Sony RED in August.
