Making playback musica sound real

[zzstation]

Hi guys,
I'm working in a tv show that has a lot of bands and artists playing live. But the sound that I have was produced in studio. The sound is really nice and clean.
I have the bands playing in a theatre and also in a small rehearsing studio.
What would you use to make the playback sound natural?
Thanks,
zzstation

Speakerphone, Altiverb, more Speakerphone, and then some creative EQ'ing to reduce high-frequencies depending on camera POV. Maybe upward compression at the start, too.

The film "Almost Famous" dealt with this issue really well.

Simple equal and reverb.
Maybe a bit of added distortion to dirty it up a bit.
