Good idea there Dale.
Here's sort of a question/suggestion that depends on the Legal parameters of the answer that would most likely have two answers. Here goes:
In your lisencing agreement with publishers/composers do you have the right to:
(1)Create a 'replica' of the original (p) published work? (2)Use these 'repicas' as you see fit? (3) Record these 'repicas' onto media and sell these paying mechanical rights?
OK, here's the suggestion for what I think, to the best of my knowledge has not been done, Sound Choice.
You already have your musicians lay down tracks for the 'replica'. Why not take those individual tracks, ie lead guitar, drums, bass etc and individualize them on separate tracks.. The end product would be a disc that a bar band could buy, and learn the song.
The bassist could play the track 'Bass' and it would be the whole song, but ONLY the BASS part, so he or she could learn the part.
The other tracks could be Lead Vocals, violin, steel, etc. What ever the 'replica' calls for.
You could sell these discs to bands either direct or through music stores.
I bet you could get $50.00 for each disc that would just be ONE SONG
LEARN CREED'S MY SACRIFICE
Disc includes lyrics, the 'mix' of the whole song, and individual tracks for all the instruments.
I bet there is some UNION haggle here but you could set up a new license to cover the musicians agreements for 'unconditional use' of the replica, and pay the musicians a little above scale.
Just a suggestion,
