I can't tell you how much I dislike Aerosmith as a rule. Basically, the best you can say about them is that they're a pretentious version of The Yardbirds crossed with a slicker, irony-free version of The New York Dolls with a flag of their collective dick up front.
That said, the above record is a masterpiece. Great music mated to an extremely well-written lyic about a serious subject.
I should add that Liv Tyler just turned 44. Yipes. I should also add that I was hoping to post the incredible version of said song the band did on SNL, but I couldn't find it.
