Puerto Rican/American composer Roberto Sierra wrote the 'Concierto Evocativo for Horn and String Orchestra' in 1990 and it was first performed by the Espoo City Symphony Orchestra in Finland. The Miluwalkee Times writes of thispiece: '...shows great imagination and artistry....Without relying on the colors and textures of percussion wind or brass instruments and featuring a solo instrument not usually counted among the 'evocative ' Sierrafashions music that is packed with energy and interest.'
