Heather is primarily a fiddler, both accoustic and electric. She also has what I can only describe as the most bloodthirsty alto I've ever heard:

She's more or less gone solo now. But she and her old band (Phoenyx) used to do a really hard-driving and energetic style of Celtic fusion/rock, and were based in the Bay area.

Nowadays, you are most likely to see her on either the Ren-Faire circuit, or the SciFi/Fantasy-con circuit (she's been known to play with the likes of filkers such as Leslie Fish and Joe Bethancourt).
