According to Wikipedia is was not David Bowie but Brian Eno who said those famous words about "I feel Love":

According to singer David Bowie, who was then recording his Berlin Trilogy, his collaborator Brian Eno "came running in and said, 'I have heard the sound of the future.'... he puts on "I Feel Love," by Donna Summer ... He said, 'This is it, look no further. This single is going to change the sound of club music for the next fifteen years.' Which was more or less right."

You should read the Wiki about this song... it is fascinating to read about the synthesizers of that time.
They used a Moog Modular 3P and:

"As the Moog went out of tune quickly, it had to be recorded in bursts of twenty or thirty seconds before being retuned." smile

We have an easy life these days...
