Soleilmoon Recordings has an excellent catalog of experimental, ambient and industrial music, including their own releases. Their paper catalog uses such a small font, a magnifying glass is needed. I prefer their web catalog, I mean I'm already half blind as it is. They have excellent prices. They specialize in the good side of progressive music, if ya know what I mean.
Cadence magazine is a great resource for the various forms of jazz.
But now you can save your eyes and perform searches via their on-line catalog. Check it out. Andy from Chicago maintains a web page devoted to Live Show Listings for different US cities.
