I think this is better suited for the "Ambiance" or "Techno" genre rather than the "Classical" genre.
In other news, the build up around 1:05 is really fun. Literally pulled my attention right when I was passing it off as just random ambiance noises. I'd recommend a shorter intro though. Its all well and good when you have the listener's attention, but I think 60 seconds can cause people to lose interest rather quickly.
