Aerosmith + Slash

Even though Aerosmith's most recent record, 2012's Music from Another Dimension!, is a largely dull affair, any band that can boast Steven Tyler, Joe Perry and a back catalog of hard-rock classics is going to pull out the stops live. Also onboard are Slash and the Conspirators—expect some lick-swapping between Perry and the former Guns N' Roses guitar-slinger.
