Audition coming up

[fern]

Hello!

I'm currently going into my freshman year of college and will be auditioning to be placed appropriately in one of my school's orchestras. The only criteria I have been given for audition music is:

Prepare 6 to 7 minutes of music to play at the audition. Contrasting excerpts from solo or orchestral literature are best: something fast and flashy, plus something slow and lyrical.

What should I play in order to meet all this criteria? How many excerpts should I play?

(I am a fairly strong player, I have played the Hayden and other pieces similar to its difficulty). Thank you!
