The soundtrack for Borderlands 2 is now available, released as a 23-track album which is digital only for now: a physical release is due October 8th.
The original score, composed by Jesper Kyd (Assassin's Creed), Cris Velasco and Sascha Dikiciyan (Mass Effect 3), with additional music from Raison Varner (Gearbox Software), is an eclectic mix of styles that matches the game's mix of Western and sci-fi themes.
The physical version can be pre-ordered for £8.99, while the digital version can be downloaded for £7.49.
However, the album doesn't contain the game intro's song, performed by The Heavy. You'll find that on their album The House That Dirt Built.
