We kick off our definitive A-Z list of classic rock artists with Australian heroes AC/DC.

For 40 years now, the group -- led by guitar-wielding brothers Angus and Malcolm Young -- have consistently proven their ability to mine a seemingly endless series of classic riffs and songs without ever straying from the no-frills hard rock sound of their early days.

They're still one of the best and most popular live acts on the planet, and fans are eagerly awaiting the follow-up to their last album, 2008's well-reviewed 'Black Ice.' Now, if you think there's a better classic rock band to represent the letter "A," please let us know by voting below.
