CLASSIC US BROADCAST RECORDING FROM 1977 By the summer of 1977, AC/DC were ripping things up across many parts of the world. Bon Scott had joined the Young brothers to form AC/DC three years earlier, and the group's first worldwide release, High Voltage, was issued in 1976. The album release garnered the group a large following in the UK, where Sounds magazine sponsored their UK tour. AC/DC's first American exposure was through Michigan radio station AM 600 WTAC in 1977. The performance included on this 2LP set was recorded for a live FM radio broadcast at the legendary Old Waldorf in San Francisco. With near perfect sound and a set-list that included tracks from all their albums to date, along with the preview of a couple of tracks from 1978's Powerage, this show was clearly one hell of an AC/DC gig and remains a classic illustration of where the group were at this juncture in their career.
