I've been listening to KJazz 88.1 FM's
online stream, and it's fantastic!
They play both Jazz and Blues. The hosts often provide history and put the pieces played in context with the history of the time.
They have a large chunk of evening programming dedicated to Blues, and I am really digging them! In a sense, I may enjoy listening to Blues more than jazz. It's very pleasing music to me.
The station plays lots of music, very little advertising, and the program hosts are great; very informative. The station is based out of the California State University system.
This music (both jazz and blues) is great! I find it very pleasing and often smile just hearing it. I also find the voices of the female vocalists to be quite beautiful. And I love when the instruments are played in a way that it sounds like they are singing too! Fantastic stuff.
