If a particular French/Breton tune in a session or dance seems somewhat familiar, it's worth checking whether it was played by Blowzabella. They have left a lasting mark on the scene.
They play a lot of French/Breton for dances, as you would expect, not so much English. Remarkable music, good for getting to know bourrées and schottisches.
