En Tol Sarmiento is one of the most important groups within the musical scene of Euskal Herria. Their catchy melodies have managed to reach an increasingly large audience. The group was formed in Iekora (Rioja Alavesa) in 2005 by three of the five members who currently make up the group. After four studio works, the group is currently presenting their latest project, Ametsetan (DVD/Documentary), in numerous venues across Euskal Herria. They have a powerful, energetic live performance that manages to make a large part of the audience dance, laugh, and be moved.
