1975年7月乐队开始录制第二张专辑《T.N.T》。12月，乐队同Atlantic公司签了一个世界范围的合约。此时AC/DC已成为澳大利亚最有名的乐队，而《High Voltage》专辑已达到150万张的销量。 1975's TNT was AC/DC's second full-length release in their native Australia, and when its highlights were combined with the previous year's High Voltage, it would result in the band's 1976 international debut, also entitled High Voltage. Confused yet? Quite understandable, as it was the songs culled from TNT that provide the backbone of that international release, including its title track and the flawless first album side, containing such classics as "The Jack" and "Live Wire." The proto-punk crunch of "TNT" is also introduced, along with a remake of the group's very first single, "Can I Sit Next to You Girl," first released two years earlier with original singer Dave Evans. While of little interest to the casual fan, this hard-to-find package does offer completists some choice treats, including a faithful cover of Chuck Berry's "School Days" and a first glimpse of concert favorite "Rocker," later re-recorded for the Dirty Deeds Done Dirt Cheap LP.
