Anyone who is an electronic music fan, I suggest that you check out a guy called 'Kebu'. He does his own pieces plus covers of work by Vangelis, Jean Michele Jarre and Jan Hammer. I've never seen or heard anything like it, he arranges his keyboards in a pentagon around him then stacks the gear three high.
Here are a couple of samples:
(Rendezvous 4)
(Blade Runner Opening Titles)
He also does excellent copies of Moroder and Tangerine Dream as well.
