Sydney – Australian music pioneer George Young, a driving force behind AC/DC which was fronted by his brothers Angus and Malcolm, has died aged 70, the band and his publishing house said Monday.

Young shot to fame in the 1960s as a member of Sydney-based The Easybeats and became an established songwriter, penning classics like “Love is in the Air” and “Friday on my Mind” with long-time collaborator Harry Vanda.

“George was a pioneer who, with close friends Harry Vanda and Ted Albert, created a new sound for the Australian music industry,” said Albert chief executive David Albert.

Fellow Glaswegian and Cold Chisel frontman Jimmy Barnes also paid tribute, tweeting: “George Young RIP.What a huge loss for music.A great songwriter, producer and a great human being.”
