Yes, I’ve heard of Bruckner, but NEVER had I heard of Abendzauber before. Get this: “Among his most unusual and evocative compositions is the choral Abendzauber (1878) for tenor, yodelers and four alpine horns. It was never performed in Bruckner’s lifetime.”

Conductor: J. Böck
Soloist: J. Gisser
Vienna Vocalists, Ensemble of the Vienna State Opera Chorus
Horn ensemble of the Vienna Symphonic Orchestra
3 Sopranos: Yuan Ming Song, Özlem Bulut, Jozefina Monarcha

I must say, though, that those don’t sound quite like yodelers I’ve heard before!
