I liked Rushmore (the movie) a whole lot when I saw it opening day. I remember the theater was pretty packed, and my friend and I were the only ones who cackled consistently throughout. The "humor" was pretty offbeat, I suppose. No stereotypical Bill Murray "Can I just say something? I love this guy right here" breaks in the movie. Just some dark, dark, awkward humor.
That said, I bought the soundtrack a week after I saw the movie, and a bought the video several months later when it hit the stores. Now I wouldn't say I'm SICK of the movie; but I definitely don't enjoy watching it over and over. This soundtrack? Oh yeah.
I didn't grow up in the 60's, so my exposure to the British Invasion was pretty nostalgic in nature. Sooooo.... I've never had the privilege of hearing The Kinks' somber "Nothing in This World...", The Who's just-long-enough mini-rock opera "A Quick One...", or any of the other more obscure (yet more wonderful) songs by Cat Stevens, Creation, Unit 4+2, The Faces, and so on. Oh, and Chad and Jeremy? I used to HATE "A Summer Song." Too cheesy. But the way it's pasted on this soundtrack? Ooooh! Great stuff.
Mark Mothersbaugh's score is perfect narrative music too. See the move, then get the soundtrack.
