AC/DC happens to be an Australian rock group established in Sydney in 1973 by Scottish born brothers Malcolm and Angus Young. Their whole music has been variously defined as hard rock, blues rock, and heavy metal; even so, the band themselves identify their tracks as simply "rock and roll".
AC/DC went through more than a few series transformations prior to launching their first album, High Voltage, in 1975. Members eventually stabilized around the Young brothers, singer Bon Scott, drummer Phil Rudd, and bass guitar player Mark Evans. Evans was substituted by Cliff Williams in 1977 for the recording Powerage.
In February 1980, a few months following producing the album Highway to Hell, lead vocalist and co-songwriter Bon Scott passed away of serious alcohol poisoning.
The band took into consideration disbanding but remained together, taking in Brian Johnson as replacement for Scott. After that year, the band unveiled their first release with Johnson, Back in Black, which they dedicated to Scott's memory.
The album released them to new levels of accomplishment and started to be one of the best selling albums of all time.
