The shift from Iggy and the Stooges to Morton Feldman is interesting. That's it.

He was also influenced by something said by his friend, the Indian music teacher Gita Sarabhai, who he remarked came into his life ‘like an angel from India’, completely changing the reasons why he wrote music: ‘The purpose of music is to quiet and sober the mind, making it susceptible to divine influences.’ This makes more sense the older you get, and roughly speaking takes you away, a little bit, from Iggy and the Stooges, as divine as that can seem and closer to, say, utopian experimental composer Morton Feldman.
