Those of you who are going to the Eisteddfod can meet trac people in Ty Gwerin, where they always have a stand round which people congregate to hold impromptu music sessions.
They organise the fantastic BEAM (Big Experiment/Arbrawf Mawr), which I have attended for the past two years on Anglesey. This year, BEAM is going south to the Stackpole Centre near Pembroke.
BEAM is long weekend of Welsh folk music for instrumentalists and singers. The singing workshop with Arfon Gwilym is awesome. Arfon runs it in Welsh, but has an interpreter along, armed with headphones for those who need a simultaneous translation.
The instrumentalists get top people like Steven Rees as tutors. The groups are split into beginners, intermediate and advanced groups. The advanced group gets the guest tutor, who is an eminent folkie from outside of Wales. This is seen as a way of building bridges to the wider folk world. Last year, we had Alistair Anderson. The guest tutor also runs a joint workshop for all participants, in which everyone takes part at whatever level they can manage and the whole is put together into one performance piece.
Last year, there was also a separate harp group with Robin Huw Bowen, while the year before, Sian James tutored a group that focused on singing with the harp.
I've already booked BEAM for this year (first days of November). It's become the high spot of the year for me.
