[LAU] classical concert needs mixing/mastering

[Grammostola Rosea]

Hi,

My sister did an great project with here school as a music teacher. See 
let her students perform an classical concert. They played Haydn.

The recording is done with an zoom H2 I think. I was wondering if its 
possible to improve the sound and how?

Which apps and which plugins?

If an experienced mixer would take look at it, would be great.

Here is the first part:
