AC/DC released T.N.T. on December 1, 1975, through Albert Productions in Australia and New Zealand. Their second studio album followed the Australian High Voltage earlier that year, although the song “High Voltage” appeared on this follow-up. AC/DC’s first two albums would later be reshaped into a different introduction for listeners overseas.
At Albert Studios in Sydney, producers Harry Vanda and George Young worked with a band that had acquired bassist Mark Evans and drummer Phil Rudd since its debut sessions. Bon Scott sang, Angus Young played lead guitar and Malcolm Young handled rhythm. George, the guitarists’ older brother, helped turn their ideas into finished songs. Malcolm described their working method in a 2003 interview with Billboard, republished in 2017. The producers pushed the band to find titles and develop songs around them, with writing continuing inside the studio. He remembered Angus supplying “T.N.T.” as a title while Scott contributed ideas of his own. There wasn’t a long separation between writing a song and making the record.
That process also shaped the opening track, “It’s a Long Way to the Top (If You Wanna Rock ’n’ Roll).” Malcolm recalled George hearing something in the ringing guitar chords that suggested bagpipes could answer the lead guitar. Getting that sound onto tape required a little ingenuity. “Bon actually could play flute, not bagpipes,” Malcolm said. Scott recorded the melody, and the drones were recorded separately before the parts were combined. The unusual instrument grew out of what the guitars were already doing.
George’s intervention on “T.N.T.” was simpler. Angus had been chanting to himself in the studio when the producer suggested recording it. As Rolling Stone recounted from the biography AC/DC: Maximum Rock & Roll, that became the song’s “Oi!” backing vocal. Against the three-chord riff and Scott’s boasts, the chant gave the track another voice without making the arrangement busier. The title song and the opener found very different ways to make their hooks stick.
Scott also had room to change character across the record. “The Jack” slowed into blues and used card-playing language for its sexual double meanings. “Live Wire” carried a more threatening mood and became an opening number in the band’s concerts. Those songs gave the album a different pace from the title track’s blunt refrain, with Scott moving between a storyteller’s sly delivery and outright confrontation.
“It’s a Long Way to the Top” gained a visual identity in 1976 through a promotional clip made for Australian television’s Countdown. AC/DC performed for the camera on the back of a truck moving along Melbourne’s Swanston Street. The bagpipes that had required a studio workaround became part of the band’s public image, too.
When Atlantic released the international High Voltage in 1976, it drew seven of its nine tracks from T.N.T. and only two from the Australian debut. The first five songs retained their running order, from “It’s a Long Way to the Top” through “T.N.T.” “Rocker” and “School Days” were left out, while “Little Lover” and “She’s Got Balls” came across from the earlier album. Much of the music introducing AC/DC abroad was their second Australian album, repackaged under the name of their first.
