The Razors Edge is the twelfth studio album by Australian hard rock band AC/DC released on 21 September 1990. It was a major comeback for the band, featuring the hits "Thunderstruck" and "Are You Ready", which reached #5 and #16 respectively on Billboard'''s Mainstream Rock Tracks Chart, and "Moneytalks", which peaked at #23 on the Billboard Hot 100. The album reached #2 on the US Billboard 200 and #4 in the UK, a smash commercial success that returned the band to the popularity of its glory years of the late 1970s and early 1980s. The album has been certified 5× platinum (5 million copies sold) in the US, and was re-released in 2003 as part of the AC/DC Remasters series. This is the only studio album to feature Chris Slade, who was the drummer for AC/DC from 1989 to his dismissal in 1994. Background The band had recorded Blow Up Your Video (1988) with their original producers, Harry Vanda and George Young. It was a commercial success and sold more copies than the previous two studio releases combined. The Blow Up Your Video World Tour began in February 1988 in Perth, Australia. That April, on the eve of the North American leg of the tour, Malcolm Young announced that he was taking time off from touring, principally to begin recovery from his alcoholism. Another member of the Young family, their nephew, Stevie Young, temporarily took Malcolm's place on rhythm guitar. Following the tour, drummer Simon Wright left the group to work on the upcoming Dio album Lock Up the Wolves, and was replaced by ex-Firm and Manfred Mann's Earth Band drum veteran Chris Slade, whom Malcolm remembered playing with Manfred Mann during an appearance in Sydney years earlier with Deep Purple and Free. Recording and compositionThe Razors Edge was recorded at Windmill Lane Studios in Dublin, Ireland and Little Mountain Sound Studios in Vancouver, BC, Canada, and was mixed and engineered by Mike Fraser and produced by Bruce Fairbairn, who had previously worked with Aerosmith and Bon Jovi.
