I'll be honest with you Racer, I purposely left out commenting on Eno for fear of bringing down the fun we were having last night. Oh and that was such fun. But I'll give you some of my thoughts on Eno. I respect the man for his forward thinking in his interpretation of music. This takes great courage I feel. He was a true pioneer in electronic music, not so as a Thomas Dolby in the technical, but in the esthetics. I personally am not one to listen to one of his pieces for enjoyment but more for study. And the act of music study has diminished in my years.
I can see where an individual who enjoys listening to the soothing ambience of forest sounds or a gentle rain would be apt to enjoy Eno. The sense of ambience is dominant in his works. And on the contrary, some of his works are down right annoying and grating, purposely so. I can appreciate that he has a gift to invoke such emotions in individuals. That's a true gifted artist in my mind. I should mention his talent doesn't stop short of music, but he's active as an visual artist and the sciences as well. But you probably know this and perhaps might have been introduced to him through those means. Quite a renaissance man.
I think the group that your wife might have referred to was Roxy Music. But he's performed with, written for, and corroborate with so many popular/not so popular artists of the 70's and 80's. Just to list a few; Robert Fripp, John Cale, Genesis, John Cage, David Bowie, Devo, Talking Heads, U2, Neville Brothers, Peter Gabriel, INXS, and Depeche Mode. And there's also the countless Film and TV scores he's written. The size of his body of work is astounding.
Racer, to give you a vague idea of what I enjoy in music, I can personally state as.... simplistic melody. Something about this I still don't understand myself. This is probably why when asked to define the type of classical music I like, I would lean towards the Baroque era of composers. Under the ornamentation was nothing but simple melodies. Simple tastes for a simple man.
