Trio for 2 Oboes & Cor Anglais Op.87 (1795)
Allmusic: "The first movement, marked Allegro, has a comparatively nonchalant character, and sounds the most conventional of the four movements. Mozart comes to mind here in particular, but mainly in spirit and formal design. One clearly recognizes that Beethovenian busyness in the music, even despite the slightly less serious mood. The main theme, with its repeated note near the beginning, sounds a little stiff, but the movement as a whole has a fair amount of charm. The second-movement (Adagio cantabile), offers a lovely main theme, and the whole of the movement is pure Beethoven, its brilliant scoring and slow tempo being rather unusual for this kind of music at this time. The third movement carries the markings Menuetto, Allegro molto, Scherzo, but is almost a genuine Scherzo. Its fast music and muscular style give it that Beethovenian stamp, and make a fine contrast to the preceding Adagio. The finale, marked Presto, is another brilliant movement, though here Haydn steps forth, both thematically and formally. Again, however, Beethoven never becomes imitative in any passage. The music is full of humor and deft touches, and this movement, a Rondo, ends with a brilliant coda."
Here's a playlist of videos using different instruments for each of the 4 movements...
1 - M1 - Allegro, on Saxophones
2 - M2 - Adagio cantabile, with 2 Violins and 1 Viola
3 - M3 - Menuetto, Allegro molto, Scherzo, Piano Transcription
4 - M4 - Finale, Presto, Mandolin and Guitar Ensemble
followed by some extra movements I found floating around.
5 - M1, Another Sax Trio
6 - M2-4, 2 Oboes and English Horn (the original arrangement)
7 - M4, Oboes and English Horn (extremely fast version)
Some of these performances here are by student musicians so be warned that you're going to hear some "Xenakis-like" moments here and there - but they're still kind of interesting IMHO.

Beethoven also wrote an Oboe Variation as well - but without switching instruments of course ;)
