Let me know if/when you are taking submissions I'll let my pianist know about it. Also, how difficult should these tunes be?
My opinion is that they should be the kind of tunes that a competent jazz group can play with little or no rehearsal. The goal is to put music out there local musicians want to play. that are good tunes, and that don't require royalties. I often get charts plopped down in front of me on certain gigs, and just have to play them. So if there are a lot of nuances, time changes, feel changes, and stuff you kind of need to listen to, orchestrated parts to fill in the blanks, people don't call them. See my post above about the Pat Metheny Real Book....
I'll let you know when ready to take submissions. People have already been sending me stuff, but I do need to get the licensing ducks in order so people know what they are giving up. Coming off a wicked cold, wedding reception for my daughter, and family down these last couple weeks and only feeling myself, barely today. Really enjoying the discussion though.
