One that came to mind this morning, Frank Reizensteins Concerto Popolare. There is a second where the music stops and you dont quite know where they are... Here is the YouTube link http://youtu.be/PVC1AkIJh68
Also a mention of the Spike Jones version of the Nutcracker Suite. I have the Catalyst BMG CD release from the early 90s. Parts would not be done this way now, Chinese Dance especially. But the arrangements and some of the wordplay in the lyrics, Waltz of the Flowers comes to mind, is fantastic.
Some people will consider a Winterreise accompanied by wind quintet
and accordion odd. I find that it works perfectly. Christopher
Prégardien has recorded it this way with the arrangment by Normand
Forget. I would say that the "komponierte interpretation" by Hans
Zender, which Prégardien has recorded more than once, is odd. I
listened to it once and vowed never to do so again.
