Philip Glass has to be the most recognizable composer alive, simply because his style is so unique. I hear people copying Glass a lot now, however, which has more than once confused me. They usually only copy him so far, then throw in some things that Glass would never do.
Interesting thread. I hear a lot of film music in which I instantly recognize the composer, even if I don't always know the name. I'll just know that he's the one who composed such-and-such, and further research usually bears me out. Film music has changed so much since Jerry Goldsmith's era. It was about the time that ET came out (the movie, not Entertainment Tonight) that it seemed Hollywood had developed a new style, and for a while it seemed that many composers used the same style and even quoted each other. It is becoming more diverse again, but for some time it seemed quite barren, creatively speaking, as if audiences were expecting a certain sound and would walk out if they didn't get it. I tend to generalize, but I'm sure most of you know what I'm talking about, even if it isn't as pervasive as I make it sound.
By the way, this is my first post in this forum. The topic was interesting, so I joined.
