Same. Back in middle school when The Real Thing came out and they blew up we were all in to Epic and everything for a while but it wasn't too long before we all found Introduce Yourself and THAT album was a real revelation, on par with the first time I heard Frank Zappa or the Butthole Surfers' good period, or Black Sabbath, or Bo Diddley.

I'm pretty sure The Crab Song was the first music I ever heard on CD.
