Mystery and Misery is a well designed, articulate website that links to bands around the country that I’ve never heard of. The descriptions are dead on, and the site even provides a ton of mp3 links to the bands being discussed. Make them a bookmark.
Start your downloading engines, because there’s a ton of good stuff to be found. For example, be sure to check out the mp3s from Maine’s Seekonk. You’ll like them, I know you will.
