Rosa operates in between: in between composed and improvised, in between music and theatre, in between light and serious, in between acoustic and electronic, traditional and experimental, classical and popular. Rosa is constantly on the move and produces music, theatre, performances, concerts and albums – often in cooperation with other artists. Their music is playful, exciting and theatrical, but also strange, unruly and elusive. The ensemble was founded in 1997 with their first performance Diepe Wildernis, based on the famous book by Brazilian writer Guimaraes Rosa, who gave the ensemble its name. In the course of the following twenty years Rosa slowly drifted away from the idiom of contemporary music.
