The guy who started the band celebrated his birthday yesterday.

Malcolm Young formed AC/DC back in 1973 and asked his brother to join the band.

He was born on January 6, 1953 in Glasgow, Scotland but of course he grew up in the Land Down Under.

A great rhythm guitarist who has developed many of the band's guitar riffs and is known as the business and brains behind the band, Malcolm might not be as flashy as his brother, Angus, but he's a powerful force nonetheless.

2013 marks the 40th anniversary of AC/DC, and they can also look forward this year to their "Back in Black" album being honored and inducted into the Grammy Hall of Fame, joining a diverse group of 27 other albums that "are memorable for being both culturally and historically significant."
