I find most of the jazz standards boring, but I don’t care what you listen to. He is to popular music as Miles Davis was to jazz. Kind of Blue is one of Eno’s favorite albums. It would be nice if people didn’t bash what they don’t like or understand.
Eno like others was experimenting with synthesizers. He has worked and helped some of the most popular acts of the time.
He and others(Fripp, Daniel Lanois, etc)pretty much invented ambient music. On his album My Life In the Bush of Ghosts, along with David Byrne, used sampling, which is now used extensively. They introduced world music to rock and other genres.
Groundbreaking yes, talented yes, quirky yes, boring no, poor producing no. He will be remembered as one of the most influential musicians of the 20th century.
