My Fear for Cadenzas

Recently, I read a post on David A. Wells's blog. In it, Mr. Wells details the process by which he wrote his own cadenza to the Mozart bassoon concerto. It's an interesting piece, one which had more than a few links to good material. In fact, I was surprised to learn that there is a D.M.A. thesis by a bassoonist named Sarah Anne Wildey, titled Historical Performance Practice in Cadenzas to Mozart's Concerto for Bassoon K. 191 (186e).
