As RedRiver patrol said, I would happily give a donation towards the production of a new CD.
Recently English prog band, Camel asked their fans to help fund their new DVD as follows:
$30 gets you the DVD and acknowledgement in the newletter.
$40 gets you listed in the DVD credits and your copy signed by the band.
So, while it's not original, it has merit and I think an excellent way of keeping bands "afloat", to coin a phrase.
Wasn't it the Ozark Mountain Daredevils who said: "Makin' a livin', not a killing"?
