Australian band AC/DC, formed in 1973 by brothers Angus and Malcolm Young, became one of the biggest rock acts in the world. With albums like "Highway to Hell" and "Back in Black", AC/DC created timeless hard rock anthems. Their raw riffs and high-energy shows earned them global fame. A lesser-known fact is that Angus Young has worn his trademark schoolboy outfit since the band’s early gigs, inspired by a suggestion from his sister.
