I'm with Beag, give 'em it, warts and all.

Maybe a DVD - they hold more data.

No, I don't know, probably not then.

I recently had a problem similar to Karyn's. What I did was to set up a drop box and email a link to all involved. I told them to take the files they wanted and kept it active for 48 hrs. It saved me from compressing the files for space and then emailing it out it bits and pieces.

Just trim everything between "HELLO"  (first power chord)........ to ............(last power chord fades to feedback)...... "GOODNIGHT, YOU'VE BEEN A BANGING CROWD......WE LOVE YOU".
 
That should fit nicely on a CD with no problem.

Gobbler.

I say give em 2 CD's and exactly what they played. They might even want to throw money at you to let them come in and do some 'overdubs'. 

I'm all for people throwing money at me.

fixed.

You can send large files through gmail with it's Gdrive feature so if any of them has a gmail account they could just download the waves and do with them what they will. That of course would mean moderate computer shenanigans though and I know some musicians (especially some of my old rocker friends) might not know how to deal with that.
 
I find just posting streams on soundcloud does something to the sound (I know there is some data compression so if I'm not imagining it that's probably what's up). There is also dropbox but that's more confusing than gdrive.
 
I have not however used gdrive yet (because I have a dropbox account and haven't really switched yet). I'm not sure what the file size limit is but you could do it in chunks of a few songs at a time.
 
Then in the meantime you could hand them a "greatest hits" cd for immediate consumption/posterity.
 
 

Oh and since you did the recording multi track (if I'm reading that right) you could "cheat" by getting the guys to overdub the mistakes and try to match the sound to the live recording (via reverb, saturation, eq, etc). That seems to be pretty common for live albums anyway these days.
 
I'm going to be doing some "enhanced" live stuff that way for some old recordings that have some major problems like some instruments are completely inaudible (like my acoustic guitar) or non existent (as in we didn't have a bass player but the material would very much benefit from it) where I'm going to completely overdub those parts and blend them into the existing stereo mix.
 
Should be fun... lol
