The song from him that I remember the most is the World Cup 2002 anthem. It has 3 versions: one original orchestral theme, one modified anthem, and one synthesized anthem.
I am into music-composing too and I have composed several tracks for Aevarrian Coliseum 2 and my upcoming strategy game... Let's just say Vangelis is my inspiration.
There is more info on him at Wikipedia, even with his photo.
