If we're going to get into older music, I have to mention the stuff I grew up listening too. I wasn't alive when it came out. But when I was younger, my dad got me into it. I'd have to say....
Frampton
Boston
Supertramp were the big ones.
Also, with my buddies, I got into Zepplin, Van Halen, and Sabbath. And yes Theridos, While Ozzy was in the band. soooo good in those days.
