Rock or Bust Rock or Bust Rock or Bust is the 16th studio album by Australian hard rock band AC/DC. It is their fifteenth internationally released studio album and the sixteenth to be released in Australia. It is the shortest studio album ever released by the band; at approximately 35 minutes, it is two minutes shorter than their previous shortest album, "Flick of the Switch", which was released in 1983. The album was released on November 28, 2014. "Rock or Bust" also was the group's first album without founding member and rhythm guitarist Malcolm Young, who had retired from the band in 2014
Malcolm Young volume with little or no gain. This is contrary to a common belief of many rock guitarists that rhythm guitar should involve loud and overdriven power chords through large amplifiers. Dave Mustaine of Megadeth stated in a 2004 interview that he considered himself, Young, Rudolf Schenker and James Hetfield of Metallica to be the best rhythm guitarists in the world. In 2006 he was the subject of a song (and album) title by Australian punk rock band Frenzal Rhomb: "Forever Malcolm Young". In 2017 Gretsch guitars reissued the Gretsch G6131MY, a ‘signature’ guitar based on Young's modified 1963 Gretsch Jet
