No nonsense ways to improve live concert recording?

I have a concert recording i’d like to improve, all the songs look like this in audacity:

in my limited knowledge all I can tell is that the volume is too low and it’s mono? What are some things I can do to improve these tracks that isn’t too complex?

On audacity 2.1.2

It is not mono. It is stereo, and left and right appear different.

The volume is only a little too low. Do you want to remove the dynamic range so that it just sounds universally loud?

I suggest you post an audio sample and tell us what you think is wrong with it now.

Yes, how would I reduce the dynamic range?

Nevermind I applied some bass and treble adjustments then used the compressor to reduce dynamic range, didn’t know that’s what it needed. Sounds great now, thanks.
