Besides his work with Roxy Music, I think I see more discussion about Music for Airports than anything else he's done.

But maybe I exist in strange circles.

Outside of music critics, I don't see him talked about much at all. I love his work as a producer for John Cale, David Bowie, and the Talking Heads in particular. Iirc he also worked on the two Iggy Pop records (the Idiot and Lust for Life) that Bowie produced. I also like his solo (non-ambient) work and work with Roxie Music, but the style of singing isn't my favorite. I know he didn't do vocals for Roxie, but the style of singing is similar to me.

He had a great conversation with Rick Rubin on the Broken Record podcast.

To be fair it could be me who’s in those strange circles :)
