Brothers Malcolm and Angus Young weren’t the first famous musicians in their family. Older brother George played in an Australian band called the Easybeats, which scored an international hit single. Inspired by George’s success, the younger Youngs started a band of their own in 1973, naming it AC/DC after seeing those letters on a sewing machine. The band has since sold more than 200 million albums worldwide. —Jeff Royer
