Even though they program a lot of 20th century undersung music too, I think a fair number of people might like this (https://itunes.apple.com/us/podcast/classical-podcasts-podcast/id381153201?mt=2) podcast (not sure I have it right. Search Buried Treasure @ iTunes Store, look under podcasts for Classical Podcast...) Most recent episode has works based on literature, by Gerhard, Debussy, Koechlin, Bernhard Herrmann; an earlier podcast had, after a movement by Reger, quartets by Martinu (5), Zemlinsky (#2 in D), Prokofiev (#2), Toch (a somewhat early one), Pijper, others- 2 hours of quartet music of interest and enjoyment (I thought. Part of a 6 part series devoted specifically to Modern String Quartets; other episodes may be of more interest to other listeners, and so don't download those that don't interest...). Also 2 programs of interviews with Jon Vickers, iirc, broadcast recently...
Caveat: large episode filesize (200-300-plus MB). For those for whom some at least of these things- the interview w Serebrier? - sound to be worth checking out- link provided :)
