How could I have missed such a masterpiece!?! This Danish video, dating of 2013, is a rarity on several points. First of all, 'næse fløjte' videos from Denmark are rather scarce. But also classical music played with a nose flute, and particularly when the musician uses props like a tuxedo in the vid. "Haydns trompetkoncert på næsehorn" ('Haydn Trumpet Concerto on a Nose Horn' [næsehorn means rhinoceros in Danish]). And even rarer, when the piece is played on a vintage instrument!
Indeed, the title page shows the instrument, and it clearly is a German oldie, with its pair of folded flaps (no rivets). In fact, it is exactly the same instrument than the first German vintage nose flutes I acquired some years ago, from a... Danish antiquarian.
