There’s a good reason why Alter Bridge are regularly touted as future festival headliners; they’re an immaculately precise and consistent live act. This set, taken from their triumphant O2 Arena show in London last December, is proof of not only how expertly they command the live environment, but what a stellar setlist they’ve put together over the course of their five albums. Alongside the entire gig is a disc of rare material, including the superb, never-before-released Soundgarden-esque Cruel Sun. If you’re a fan it’s all you could ever want, but for all the professionalism there’s the sneaking suspicion that this lacks the off-the-cuff, rough’n’ready charm that made classic live albums like Live And Dangerous or No Sleep ’Til Hammersmith such essential purchases. Impressive, but your record collection is complete without it.
