This Friday is Bandcamp Friday. (Every first Friday of the month.) That means this great site, which already gives the lion's share of the purchase price back to the artist, gives even more. About 93% of the sale price. Here's their listings for gypsy jazz.
I know there are several forum members that have music on Bandcamp.
@V-dub has his stuff under Vic Wong.
@misterdanielb has a few CDs up here as ASSEO Quartet and Daniel Beja.
@dennis is there via Duved & his Transatlantic Five
The late Jon Delaney has his albums up there too.
Who else on this forum has their music up there for digital purchase?
