Lazaro: Thanks for the information. I've started to hunt around based on the information you provided and have a few follow-up questions for now:
(1) When you refer to the copyright owner, are you referring to the owner of the composition or the performance? If it's the performance, do you need permission from the label, the performer or both? And if it's the label, it's not always obvious where to go, especially if you're playing music from 78s, from LPs issued by companies that are no longer in business, or from CDs issued outside of the U.S. Any suggestions?
(2) Have you seen any guidance or information on what constitutes a "featured artist?" Does this cover just the credited leader or sidemen as well?
(3) Is there an "easy" way to determine the copyright owner on the performance?
It appears that stations affiliated with the Corporation for Public Broadcasting (which we're not) are exempt from at least some of these as a result of a private deal that they negotiated with RIAA and/or other parties. However, this doesn't help non-affiliated noncommerical stations.
This all sounds like an enormous amount of work, especially at an all-volunteer, noncommercial station. In my case, there's no indication that the station would devote any resources to help pursue or obtain the needed waivers.
