AC/DC from Greatest Rock Bands of All Time
AC/DC are an Australian rock band, formed in 1973 by brothers Malcolm and Angus Young. A hard rock/blues rock band, they have also been considered a heavy metal band, although they have always dubbed their music simply "rock and roll". AC/DC underwent several line-up changes before releasing their first album, High Voltage, in 1975; Malcolm and Angus were the only original members left in the band. Membership subsequently stabilised until bassist Mark Evans was replaced by Cliff Williams in 1977 for the album Powerage.
