I have to give props to one of the best sounding Alternative stations in the country, in my opinion- KSLG in Humboldt County, CA.
I would label this station as a true alternative station. They have a full-time on-air staff and play a great mix of music. Locally owned and operated, this is quite impressive for a tiny media market. I recommend everyone take a listen and judge for yourself. http://kslg.com/
