Tom over at Twangville, the best alternative country music web site in the world, has formed a new Last.fm group based around alt-country, americana, rock, indie, folk, blues, etc. This will be a fun way to discover great music.
I just joined. If you share our love of this sort of music, come on along. It will be fun.
Once you sign up, be sure to get the AudioScrobbler plugin for your music player(s) of choice.
