I'm guessing that you saw Marty Stewart who mostly does country but comes from a bluegrass background.
Definitely check out David Grisman who was a long time buddy of Jerry Garcia and has taken the mandolin to places where no mandos gone before. His label Acoustic Disc has lots of interesting mandolin music which is generally recorded live in his home studio with minimal processing and wonderful vintage mikes and equipment. First class fidelity.
