Peter Heise (1830–1879) was a peerless master of song and wrote one of the best Danish operas of the 19th century. Yet the six string quartets he composed between 1851 and 1857 remained largely forgotten until their publication as recently as 2017. The Nordic String Quartet’s acclaimed survey of Heise’s quartets began in 2023, and concludes with this complete 3-CD set featuring the world premiere recordings of Nos. 4–6. These works reveal Heise’s musical imagination in all its brilliance, performed with a spacious, lyrical sensibility attuned to the composer’s distinctive poetic touch.
