I recently came across a radio station on the internet that was actually really good. I highly recommend this site for anyone here that likes Old School/New School thrash whether the bands are your favorite signed bands or a kickass unsigned band that you've never heard of. The site is run by Neil Wonnell who uploads a new show every weekend at the following link.

If you're in the mood to check out some kickass thrash that you may not have heard of, I highly recommend this radio station and you yourself can join "The world wide legions of Metalmouth listeners!"
