Erotidijos is a haunting yet hypnotic tableaux Kuprevičius originally created for a Stanislovas Rubinovas theatre play staged in 1994 in Kaunas, Lithuania. The Lithuanian composer was one of the founding members of the pioneering electronic pop outfit Argo and has written dozens of scores for stage and film over the past several decades, imbuing his soundwork with a multitude of artful moods and emotive depth.
