The Search for the Perfect Etude

Etudes are awesome (citation not findable).  Take a listen through some of the least etude-esque horn studies, and discover that if you turn some of them into horn quartets, it turns out that they are better than some concertos which shall go unnamed (in this paragraph at least).

Warning for sensitive french horn players: this recording contains Kopprasch.  And Gallay, Reynolds, Saint-Saens,  and Maxime-Alphonse.
