I was totally unprepared for my first exposure to MC5.
I was eight, and a friend of mine dubbed They Might Be Giants' "Miscellaneous T" b-side collection for me. Tapes were still pretty short in those days, so she timed out what would go on side one, waited, then flipped it and unpaused the CD to finish. However, the CD was in a five CD changer, so after the last song of the album, it immediately went to the next album and started dubbing that. That album was Kick Out The Jams.
So, yeah, I'd say that was the beginning of something wonderful right there. Thanks for the post Jon.
