This double live album collects together an hour's worth of "on fire" performances from the band's lengthy 2011-2012 tours. Featuring Machine Head's signature scholarly cross-up of classic Bay Area thrash, snaking groove and Maiden-influenced power metal, the album blares with perfect sound forever and is marked by a palpable feeling that the crowd (lovingly referred to as "Head Cases") is having a blast. The setlist reads like a greatest hits collection.
