"What exactly IS "progressive" rock? I've always thought that it's a combination of excellent musicianship and experimentation leading to evolution in sound... That's certainly a good description of Rush over the years, IMHO"
Great comment. Agree. Big fan of Rush along with plenty other acts mentioned in this thread. I'd probably include Megadeth and Van Halen as well. VH wasn't prog lyrically, but EVH's playing really didn't conform to any other recognizeable genre, and advanced rock musicianship.
Faith No More - is it possible to be 'prog' without the 5-minute guitar solos?
