Piano Recital for Two

[evitaevita]

Hello everyone,

A friend of mine and me have decided to organize a piano recital in which we are going to play both of us! We are both very excited about this idea. We want to play solo pieces as well as duets. But there are some problems with the organization.
Could you help me with these:
-How long should it be?
-What kind of pieces should we play?
 I mean: should we play, for example, each of us a baroque, a classical and a romantic piece or something like that?
-We are going to separate the recital into two parts. Should each of us play in a different part? What about duets?

Any answers to one or more of my questions are appreciated.
And, of course, other ideas are welcome!

Help you in advance for your time,
Evitaevita
