Jean Michel Jarre discusses the background for his spashing continuation from Oxygène, Oxygène 7-13, in 1997.

Oxygène 7-13 (Wikipedia)

After years of experimenting with new technology, with Oxygène 7-13 he returned to the analogue synthesisers of the Seventies. The album was released in 1997, more than 20 years after Oxygène, and was dedicated to his mentor at the GRM, Pierre Schaeffer, who had died in 1995.
Eschewing the digital techniques developed in the 1980s, in an interview for The Daily Telegraph he said:

The excitement of being able to work on sounds in a tactile, manual, almost sensual way is what drew me to electronic music in the first place… The lack of limitations is very dangerous. It is like the difference for a painter of getting four tubes with four main colours or being in front of a computer with two million colours. You have to scan the two million colours and when you arrive to the last one you have obviously forgotten the first one. In the Eighties we became archivists and everything became rather cold as a result.
