This recording is a must for horn players and aficionados! Wallendorf and Willis, both hornists with the Berlin Philharmonic, deliver technically masterful and musically exciting performances, playing three of the four known concertos for two horns written by Antonio Rosetti. (The fourth can be heard on CPO 999 621.) This includes the oft-recorded E-flat major concerto that is usually (and erroneously) attributed to either Joseph or Michael Haydn. These performances are more driven than the lovely yet somehow-too-polite recordings by the Tylsar brothers, and more musically sensitive than the bravado-laden blows of Hermann Baumann. It's quickly become one of my favorite horn CDs (and I have a lot!).
The Notturno, while pleasant, is really just an afterthought.
