My brother and I, also...Rush and Yes are tied for #1.
I like Rush, Yes, and check out the list of groups I got into around my teen years that alienated me from the KISS/AC-DC popular bunch:
Jethro Tull
King Crimson
Tangerine Dream
Uriah Heep
Kraftwerk
DEVO
Needless to say, I didn't get laid much back then...
