Having just returned from Rennes in Brittany, I have to recommend the session I attended at La Cité D'Ys, Rue Vasseloff last Tues. The session was led by two excellent fiddle players, and attended by a number of musicians including a very good flute player who also played a half-set of Uileann pipes. The standard was very high and most enjoyable. I recommend this session to anyone visiting Rennes.
