The CD Treble & Bass includes two concertos by Norwegian composer Ståle Kleiberg. One concerto is for double bass and orchestra and the other is for violin and orchestra. Composed in 1999 and premiered soon after in 2000, the Concerto for Double Bass and Orchestra is unapologetically and squarely situated within the stream of 20th century composers who opted to compose with tonal constructs, rhythmic gestures that lend themselves to motivic development, clearly delineated melodic phrases, and unencumbered texture.
