You'd be surprised. I worked through SICP a few years after graduating, and after the dragon book, and it still managed to warp my brain in new and exciting ways.
Congrats on making it through both. I haven't gotten to the dragon yet... For those interested, you can get a red dragon for significantly less than the newer editions (check amazon).
I'm not familiar with that one, but the table of contents looks promising. If it's even half as good as
his _Parsing Techniques: A Practical Guide_, it's worth checking out.
I never understood what people like about the Dragon book. It talks you through implementing a compiler for an imperative language in an imperative language in a very pedestrian way. Give me more theory!
