I've mentioned before that I have waves of favorite fiddlers. I'm on a Caoimhin O Raghallaigh kick, and thereafter all I listen to is Kevin Burke, and then maybe I'll dwell for a while in Old-Time land with some Bruce Molsky... But Liz Carroll is like the North Star, ever-constant in my library of favorite fiddlers. She kicks butt not only for being virtuosic on the fiddle, but also for being probably the best tune-smith this side of Ed Reavy. She rocks.
Here's a jig she wrote.
