Laura Palmer's Theme is so simple, yet effective and memorable. I'd say an all-synthesizer version would be a snap to produce with only two instruments and one or two tracks. Anybody?
As for the composer's story, it's like a musical fantasy. It's the way you'd like to believe things always work in composing: spontaneous, immediate, and while using the most basic of musical tools - in this case, a Rhodes and a cheap little tape recorder. The only thing missing from the story is a Minimoog!
