I wouldnt mind including a page for each band on the comp to make a mini-zine style insert. I really think a physical copy could be awesome, it could include a bandcamp download and we could also to have it on bandcamp to download it for a price.
My only question is, what do I do with charging for it? Start a label? Put out records? Keep doing comps? Buy everyone Denny's?
Recoup the costs, first off. Figure out what to do after you know how much money you have. Unless of course you want to donate it to somebody. Does Jason Noble still need money? Make these comps a benefit for Jason and you will be able to sell a bunch of them and help him out at the same time. Or shit, make them a comp to help Jamie get out of debt for Skull Alley. You couldn't go wrong with that, either. (I would actually really like to see that happen.) Donate to ASPCA. Name a pet cause.
When you attach a good cause to a good idea, it usually helps both mutually. If you do a zine with this, I would love to contribute.
200 might be a good number of physical copies to make, since:
A) It's a realistic number to make and not go broke
B) It's the number of free downloads available through Band Camp
If it were me, I would do 200 zines / discs through Kinko's (wink wink) and see if David Brooks would be willing to print 200 discs. Maybe do a small, DIY zine with a paper sleeve in the back to hold the disc. Include a download code for these physical copies. Not only would it be awesome, but it wouldn't be just another CD in a jewel case (which people fucking throw away.) Sell it for as cheaply as possible (less than $3 is undercutting, $5 is a little pricey unless the profits are going to a good cause,) and see how it does. If it does well, do them every quarter or annually.
I would be cautious about turning these things out really quickly without putting a lot of crafting, time, and effort into them. These days, if anybody is gonna buy anything, it's gotta be worth their money, and they're gonna want to appreciate what they just bought. People still buy the shit out of books. CD + book = book. I'm not sure how that equation just worked...but it definitely makes sense.
There haven't been a lot of steady zines in recent years, either. It would be refreshing to have a good one around.
