Norwegian guitarist Christina Sandsengen plays Gran Vals by Spanish composer Francisco Tárrega (1852–1909) in the show ‘Ønskekonsert med KORK’ on NRK1, recorded a late summer night at Ingierstrand in Norway. This is a concert with The Norwegian Radio Orchestra, and the host of the show was Atle Antonsen. You can watch the whole show here. The below video comes via her YouTube Channel. I recommend this sheet music edition via Amazon: The Best of Tarrega 33 Pieces (ed.Zigante).
