Rhea's Obsession consists of a pair of musicians each who brought in an entirely different musical background. Sue Hutton brings in experience with Indo-Celtic-Bulgarian style vocals, and a variety of percussion. Jim Field, on the other hand, has spent his time working on experimental and hard core music. And the combination, though unusual, works well. The two reflected upon their differences when naming the group, choosing the Greek goddess Rhea - the daughter of the gods representing Earth and Sky.
