Ragtime. My sister gave me the original concept recording for Christmas the year it came out, because she had heard some of it and thought it was something I would like. I loved it at once, then got the complete Bway recording, saw bits and pieces on TV (Tonys, etc.). When I finally got to see a production of the show, I was literally in tears by the end of the 10-minute opening, I was so thrilled.
I have to put in a plug for Avenue Q, too: I knew very little about it when I first heard a couple of songs, but that was enough to sell me on the cast album, and once I had the cast album, I was a die-hard Q-Tip (and believe it or not, I was a fan of the show in general before The Big Crush really set in). When the day comes that I finally get to see Q on stage, I'll be thrilled at that, too.
