Upon its release in 1980, the 'Ace of Spades' album was nothing short of a gamechanger for all forms of hard rock. Like lightning in a bottle, it perfectly captured everything great about hard rock, heavy metal, and punk, amped it all up to eleven, and came racing out of the gates at what felt like a million miles an hour. Pushing at every musical boundary, nothing was harder, nothing was faster, and certainly nothing was louder. This 40th anniversary edition contains the original album as well a bonus live disc featuring newly unearthed, 17 song, previously unreleased concert from the 'Ace Up Your Sleeve' tour.
