Small Classical Ensemble with Double Bass?

This is definitely not a double bass group BUT have a CD of some Handel trio sonatas which are combinations of
2 oboes and Basso continuo, or oboe, basson, contrabass and basso coninuo. First oboe is Heinz Holliger. It is a Denon CD out of Japan with all japanese writing inside so can't give much else but there is definietly some bass there.

Saint Saens' Basson Sonata will also give your system a fine work out on the bass side. There are a number of good ones available

George Onslow wrote several quintets and sextets and a Nonet that include the double bass. Though forgotten for much of the 20th Century, his reputation has been undergoing a renaissance in recent years.

I was able to track down the Rossini, the Dvorak and I have the Onslow on order. The Rossini in particular is lovely, if a bit light.

BTW www.arkivmusic.com is a fantastic resource.

Grimace - The Schubert Trout Quintet is the real winner in this list. A wonderful piece. I have a recording by Andras Schiff which I like a lot but there are many good versions.
