Advice for Chamber Music

[shagdac]

Would appreciate some "pointers" on playing chamber music and with orchestra. Have performed solo of course and as accompanist, but never with  Quintet or Orchestra.  Other than the obvious differences, would appreciate any suggestions on what to pay particular attention to, be careful of, etc....

***Also, does anyone know of a decent recording of the Beethoven Quintet in E flat Major
Opus 16, and is it possible to get a recording of quintet music with the piano only?

I appreciate your help.

Thank you,
S
