I have always liked steel drum music, particularly when the musician is breaking out of the traditional calypso mold (although that stuff is pretty good, too).
Dante Bucci is a musician who's just been pointed out to me. He plays the hang drum, a new invention based on the steel drum. (I want one, or at least to try one!)
There are a number of videos on YouTube of Dante Bucci playing, but you should also search for "hang drum" as well. If you prefer to listen to lots of music like this, try pandora.dantebucci.com or itunes.dantebucci.com.
