Several flutists have shown an interest in the recorder piece Birds of a Spring Night (Vårnatsfugle).
At first, the piece was transposed and changed a bit (in the version, which Kerstin Thiele performs on PACD 110).
Later, in cooperation with flutist Craig Goodmann, it was revised in order to obtain a more flute idiomatic version, which is now the final version that counts.
… fløjten er de lange melodiske åndedrag og vinden, der spiller (flerstemmigt) i et rør, man svinger rundt – og ikke mindst de korte signaler, fuglefløjtene, sat sammen på rapsodisk vis.
