Hugh's MP3 Pick:

Natalie MacMaster
"Catharsis"

Natalie MacMaster has been called "Canada's finest fiddler" and is a rare combination of flawless musicianship, broad traditional knowledge and dynamic performance. This free download is from MacMaster's 1996 release, No Boundaries, and is the first track on the page.

Also, you can check out my review of her groundbreaking 1999 release, In My Hands, which combines Celtic roots with more contemporary sounds.
