The project and ensemble "Songs" brings together Swiss trombonist & composer Samuel Blaser and pianist & composer Oscar Strasnoy, taking the instrumentation and concept of Lucio Berio's Folksongs and expanding it into Blaser's "Worksongs", a set of songs around Mississippi Delta blues, and Strasnoy's "Chanzuns Popularas Rumanchas" based on the traditional music of the Canton of Grisons.
