If you go to the Darkness Radio website and follow the links you can find a ton of shows downloadable as free podcasts. http://www.darknessradio.com/
His local radio station hosts them. They are good. When hiking nightly in the woods I like to listen to talk and found myself listening to Darkess Radio way more often than Coast to Coast. Problem is that Darkness doesn't get a lot of guests and so there is a lot of "paranormal in the news" type shows. On some nights Mallie Fox is there too and she's teh hotness. http://www.paranormalgirl.com/
When Schrader (calling him by his last name so I don't confuse the Daves*) does interview someone he doesn't stand for BS or pull punches. He had a time travel guy on several months ago, if I remember right, and really gave him a hard time. Maybe someone else can recall which show that was.
You also might remember him from co hosting the last Ghost Adventures live show on Halloween a few years ago.
There is no Dark Matter on Friday anyway. I'd suggest giving Schrader a chance and not projecting opinions of the other Dave on him. Maybe you'll like it and can fill in your Dark Matter downtime with Darkness instead of C2C.
*because it would be SO EASY to confuse that statement with the other Dave, amirite?
