HIGH VOLTAGE (1976)
Key Tracks: "T.N.T.," "She's Got Balls"
Quick Take: Perhaps AC/DC's most crucial innovation is the way their lyrics make plain the boys' locker room conception of sexuality that had previously bubbled just under the surface of most heavy-duty rock. Shamelessly sexist panderers or refreshingly frank entertainers? AC/DC fits both descriptions, but none of it would matter if guitarist Angus Young wasn't such a gargantuan riffmonger equipped with a Godzilla-like rhythm section to boot. High Voltage established that sound that would stick for over three decades.
