Maybe not the greatest music, but the greatest muscians in rock history were Emerson Lake, and Palmer. All three virtuosos. Modern era, Rush.
Agreed on ELP and RUSH.
I enjoy once in awhile to listen to Rush’s covers of some of the songs that they liked and were influenced by. The originals are the best, but fun to see Rush’s take on them:
“Summertime Blues” (Live)
