Advice on openings that grip the listeners attention?

Isao Tomita did a synth version of Gustav Holst - The Planets, the sounds in the video above kinda remind me of it…Maybe you guys will like it, quite relaxing…synth classical i guess. Nice swells in the sound like that guy in the video was talking about. ( it gets going at about 3.00 ) Really makes a difference to actually play the keyboard live…I feel i must learn it.
