Need suggestions

[SlavikSvensk]

My dad's doing a lecture/concert series here and the next one is going to be on modern music. He's asked me for a techno track to use as an example. He's specifically asked for something that has slow, gradual transformation rather than big shifts in sound and pronounced breakdowns. He wants to point out that there are subtle changes throughout the track that lead to it sound quite a bit different at the end than it does at the beginning, but for the changes to be fairly imperceptible to the untrained ear. I was leaning towards some older Surgeon Dynamic Tension stuff, but thought I would post here to see if anyone has other ideas. The Surgeon was the first thing that came to mind when he told me the parameters, but I'm open to anything.

This will be an older crowd, so I want to avoid bangers that might scare them. Hard is okay, just not ruthlessly pounding. I'm also looking for something that would be fascinating to a classical listener. They don't have to love it, just find it interesting. He's done this lecture series for years, focusing on one or two composers each year, this year being Haydn and Dvorak. This is the last lecture of the year and he's moving into the modern era composers, but wanted to have this as an example of another type of modern music while he's going through synthesizers and their impact on music as a whole.

Any help is appreciated.

for a classical crowd, i think a very good choice would be jeff mills "utopia"
