I used to produce a program entitled "If It Ain't Baroque..." - the content is pretty self explanatory, (mainly) Baroque music. One hour in length (well, about 55 minutes to account for station ID's and news at the top of the hour).
In line with my upcoming switchover to all public domain music, I'm going to be reviving the show (although I may change its name), and making it available via the ALPB (whose mandate is to assist low power stations with programming).
The nice thing about classical music programming - the original oldies - is that all the songs are in the public domain (except for some 20th century modern stuff that I don't consider classical anyway). That means that in the U.S., you can freely play such material on the radio over-the-air. The actual performances of most available recordings will still be copyrighted, and that means that they cannot be streamed without paying licensing fees.
In Canada, the music, as in the U.S., is also in the public domain (songs are the purvue of SOCAN), but if the recordings were released 1964 or prior, they are in the public domain as well (recordings are the purvue of ReSound). I plan on using only recordings of this vintage (many of the greatest classical recordings were made prior to the mid 1960s, regardless of later recordings using better technologies), so in Canada, these shows will be entirely in the public domain, and can be freely played over the air or the Internet. They can even be archived (the purvue of the CMRRA).
In short, in Canada, you will be able to do whatever you want with the shows. The music will be great, but unfortunately, you'll also get my voice - nothing I can do about that, sorry. It is what it is.
As things come closer to fruition, I'll post updates.
