i was wondering if there is a way to reduce the reverb on his one track ?

Nope. You may have some luck with a high quality downward expander, but don't get your hopes up.

You could try with an SPL Transient Designer, it allows you to reduce the tail of a sound.
It can't do magic but sometimes it's useful.

I think you may achive some success by applying a gate to the solo track to reduce the reverb tail.

A downward expander as AudioGaff recomended, is basically the same thing as a gate but allows you to controll how many dB you want to attenuate the offending reverb tail.

When you have the soloist's track on by itself, it may sound a bit chopped off but once you mix this in with the other tracks, it might be acceptable. It will take a bit of poke and hope but I have a good feeling that you may be able to achive what you are after ..

Good Luck, Kurt Foster

Yep, a great tool. In fact, I often use it for removing, albeit tentaively, reverb tails off processed drums.
