My favs:

60's - Moody Blues (They were strong in the early 70's too but started and had several great albums in the late 60's).

70's - Pink Floyd (They started in the 60's too but most of the stuff I remember of theirs seemed to be 70's vintage)

80's - Alan Parson's Project (Not sure when they began but most of their good stuff I remember from the 80's)

90's - Savage Garden (Seemed like most of the stuff I liked from the 90's is by groups that were big in the 80's)
