I just heard my local station promoting the choir contest for a Feb 13 show during my morning commute. If you know the local classic rock station who shows up out front of your venue, I'd recommend keeping your ears tuned in. If you don't know the likely radio station, you'd likely get more help from the venue than here. I've seen many radio station contests start with choral video submissions and the best move forward to live competitions. The choral director usually submits the choir in the contest.
