Mellow 70's Prog - Supertramp, Styx, ELO, Alan Parsons, Moody Bl

Created by progrocktv1000 on Dec 14, 2007

These are the crossover symphonic prog groups who became mainstream artists yet retained the elements of classical progressive music (orchestral concept albums) while filling stadiums thoughout the late 70's with a combination of AOR and top 40 type crowds (lush romantic lullabyes included!)
