AC/DC is a hard rock band formed in 1973 in Sydney, Australia by Scottish brothers Malcolm and Angus Young. They are known for their high energy live shows and Angus Young's schoolboy outfit. Some of their most popular albums include Back in Black (1980), which featured new lead singer Brian Johnson after the death of original singer Bon Scott, and The Razors Edge (1990) which helped renew their popularity. AC/DC continues to tour and record into the 2000s and 2010s with their classic lineup of Angus Young, Malcolm Young, Brian Johnson, Cliff Williams, and Phil Rudd.
