I haven't noticed anything here about the combination of yodeling and overtones, so here goes. Any aficionados out there, besides Wolfgang Saus and Christian Zehnder?
Since I'm in the process of creating some specific notated exercises combining yodeling with overtones, during a recent yodel surfing expedition, I came across this magnificent blog site called 'Yodel Heaven', which it definitely is. You'll find a huge amount of rare (downloadable) mp3s on yodeling all over the world, as well as several throat singing and overtone singing tracks. Even Arthur Miles.http://www.mademoisellemontana.wordpress.com
