High Voltage is the debut studio album by Australian hard rock band AC/DC, released on 17 February 1975. Six of the album's eight songs were written by Angus Young, Malcolm Young, and Bon Scott. "Soul Stripper" was written by the Young brothers and "Baby, Please Don't Go" is a cover version of a Big Joe Williams song. The album was produced by Vanda & Young at Albert Studios in Sydney, Australia. George Young is the older brother of Angus and Malcolm, who also played bass guitar on a number of the album's songs, and played bass guitar at some of AC/DC's live shows. Harry Vanda was a bandmate of George's in The Easybeats. George and Harry were the main songwriters of The Easybeats' later hits, including their international hit "Friday on My Mind".
High Voltage was originally released on Albert Productions only in Australia, and has never been reissued by another label in this format. The international version of High Voltage, that was issued on Atlantic Records in 1976, has a different cover art and track listing, with only "She's Got Balls" and "Little Lover" appearing overseas. "Baby Please Don't Go", "Soul Stripper", "You Ain't Got a Hold On Me" and "Show Business" were later released on "'74 Jailbreak in 1984. "Stick Around" and "Love Song" have been released on Backtracks in 2009.
AC/DC was still developing its sound when High Voltage was recorded in November 1974, and Bon Scott and the Young brothers (Angus and Malcolm) were backed by a different rhythm section than the Mark Evans/Phil Rudd combination featured on their next three full-length studio recordings. Rob Bailey and Peter Clack were the band's bassist and drummer, respectively, at the time. According to Murray Engleheart's book AC/DC: Maximum Rock N Roll, bass duties were shared by Malcolm and older brother George, who also played live with the band infrequently, as well as Bailey. George may have also played some drums, along with Tony Currenti. Clack and John Proud played on one track each. Malcolm and Angus traded-off lead guitar parts on "Soul Stripper" and "Show Business", and Malcolm played the solo on "Little Lover". George Young and Harry Vanda produced the album, which was recorded in 10 days in between gigs at Albert Studios in Sydney. The title and artwork were the suggestion of Chris Gilbey of Albert Productions
