Rock, I presume? What sub-type of Rock? I'll consult my 1997 2nd Edition "All Music Guide to Rock" - it predates allmusic.com, as well as Post-Grunge and so forth, which has distorted modern writer's appreciation of 70's Rock. Under Various Artists - there's 39 pages with roughly a dozen per page - not all of which span 70's-only, of course.
Its always best to make your own...but if you really want to buy one there is one that is definitive. The 'Have A Nice Decade' box set. 7 discs and covers everything from disco to rock. I think its by Rhino Records
