Larry,You can count on WFDU and my programs for helping to spread the message. My email address for anyone who has events they would like promoted in the NYC/Northern NJ area is wfdutraditions@aol.com. The station address is WFDU-FM 1000 River Road Teaneck, NJ 07666 You can mark it to my attention - Ron Olesko.
As you said Larry dwindling audiences is not the whole problem, but if the audiences are there it makes the other problems easier to deal with.
I would also suggest that New York City is not the only market. While it is important, there are some wonderful opportunities in the suburbs. Transportation is a problem for some of the artists - I've had a number of musicians who couldn't travel to NJ to be on my show or perform at a local club. I would suggest to musicians that they do explore the possibilities - word of mouth of a good performance in NJ, Rockland, Westchester, etc. will have a bearing on getting opportunities in NYC.
