Now see, in the past ouple of years I have really begun to "dig" the prog stuff.... It's all Petrucci's fault for getting me into Dream Theater Very prog metal.... Think Metallica having a head on collision with Pink Floyd

But I agree with the "twitch" thing... Listening to "Take It Back" from the "Division Bell" album and the hairs on the back of my neck are standing up... "Comfortably Numb" (from "The Wall") makes every single hair on my entire body stand on end, even just thinking about the song I get goosebumps..... I dunno why, there is just something electric about that record - it's like Guns N Roses "November Rain" or "Estranged", or the solo break in Dream Theater's "Lie" - they all do it to me.... But Floyd more than most I think......
