I doubt Aerosmith will ever return to that raw sound they had on Rocks, Toys in the Attic,They produced some of the best hard rock from that era. They have become to polished with to many outside influences. Bearing in mind that Aerosmith now cater for a completely differant set of fans that have bought up on a diet of Pump, Nine lives etc. I think most fans from the 70s have deserted them from Rock in a Hard Pace and onwards.
