The organisers decided to return to a primarily folky line-up which included Mynediad am Ddim, Cowbois Rhos Botwnnog, Calan and Steve Eaves.

The 2011 Sesiwn Fawr also included a twmpath dawns (a large communal folk dance) on the town's Eldon Square on the following Saturday.

Since 2012, Sesiwn Fawr has returned to Eldon Square, the festival's spiritual home, introducing bands from Wales, Brittany, Ireland, Scotland and England.

During the next few years, organisers explored other venues within the town making use of hidden away court yards, cellar bars and coffee shops, thus rebuilding a festival around Dolgellau's historical architecture.

In the past, the line-up has included Super Furry Animals, Steve Earle, The Dubliners Iwcs a Doyle, Burning Spear, Bob Geldof, Saw Doctors, Bryn Fôn, Meic Stevens, Geraint Jarman a'r Cynghaneddwyr, Derwyddon Dr Gonzo, Grupo Fantasma, Paul Dooley, N'Faly Kouyate, Endaf Emlyn, Cerys Matthews and Goldie Lookin Chain.
