I'll be in NYC june 5-9.
I want to check out the cool jazz & blues clubs in Greenwich Village. Surfing google I found Cool Cat Club Crawls atCool Cat Club Crawls It sounds like fun. does anyone know about them?

I haven't heard of the tour you mentioned, but I would suggest getting a Village Voice (it's a free weekly paper) or a Time Out New York (a weekly magazine) when you get to the city and checking their music listings. A couple good jazz places in the Village are the Village Vanguard and the Blue Note. There are lots of small places in the Village that might have blues music. I would check the listings and pick which one sounds best from there. Have a great time!
