"Bigsession
The place for young UK folk musicians, singers and dancers to come together to… To talk about festivals and gigs... To promote their own gigs to people their own age.... Post pictures of most recent festivals, gigs and sessions.... To help each other to get gigs and make contacts.. Learn about opportunities for young folk musicians dancers and singers…... Or to just praise (or not) today's folk scene and how we see our selves fitting in to it... Come and join our session, let's make a big sound!"

Loads of young folkies online, many in the Northeast, but beware, if you consider Mudcat is full of drivel then big session shows that the next generation of drivelers is alive and well (usefull to learn to speak Llama first!).
