AFD is in that category, but there's a degree to which "Which came first?" applies here. I was there, the first time, when Boston, VH1 and Appetite were released. Boston was "whoa!" because that "sound" was like nothing that came before, and Delp's voice was a breathe of fresh air. Some people started to pick up guitars to learn that run in "More Than A Feeling". VH1 was "WHOA!" because it was like hearing three guys playing at once, and yet... it was just one guy. NO ONE played like EVH, and you have to remember DLR was way cooler than he is now, and was sort of a unique voice in the way he approached his music. A whole lot of people picked up guitars to learn "Eruption". AFD wasn't that. I remember being at UConn, and living in a dorm complex called "The Jungle", and coming back to school in September and hearing "Welcome To The Jungle" out of every dorm room, but as good as Slash is (and he is great) it's not like Aerosmith didn't do a lot of that, better, and ten years earlier. Yeah, I learned the intro to "Sweet Child..." to impress chicks at parties, but I didn't go out and try to learn the whole record like I did (unsuccessfully) with VH1. Yeah, some of the lyrics were grittier ("Rocket Queen" for one) but it's kind of like "Lady Gaga"; she's awesome, but if you saw Madonna back in the day, it's not groundbreaking.
