Phish if I remember correctly started in early or mid 80s. Love them too. The improvisations/jamming can go on forever and I never get bored. Classic rock is timeless even tv shows and movies use it as a soundtrack. Con Air: Sweet Home Alabama by Skynyrd, Iron Man: Shoot To Thrill by AC/DC, A Knight's Tale: We Will Rock You by Queen, CSI: Who Are You by The Who, Sopranos: Don't Stop Believin' by Journey...the list could go on.
