Sonic Theater is a very different channel. It’s not an easy channel to visit briefly, because most of its programs are part of continuing series (some of which, like ZBS’ “Fourth Tower of Inverness”) have been around for decades, and so a one-day listen didn’t let me get into the programming to any serious degree.
I would probably enjoy this channel a lot if I had the time to tune into it on a regular basis and listen to one or more of the particular series every day.
