The 1970's saw the peak of progressive rock. Although many of the gernes forerunners continuing to sell sucessfull albums well into the 1980's. However by the late 70's to early 80's progressive rock saw a decline, many of the now veteran music groups splitting up, going through irreperable lineup changes or changes musical nature altogether.
