Blues from the 50s/60s/70s

Chashmal, thanks for your post and your comments. I think your offers us a valuable information and you can be sure that will follow your advice. I never thought that I could find this amount of great and valuable information just for posting a simple question. Now Im more interested than ever in the "blues" world.
To be more involved in this field, what about a recomendation of a good reading? will be fabulous to have one or two books about the history and evolution of the blues in the US, and maybe another one or two titles about the explosion of the blues in the UK in the 60's.
Thanks again to all, Im learning every day.

Thanks for the list Chashmal! - I there is one thing I enjoy as much as music it's a good book. I am a blues fanatic and never really read anything about the subject. I am sure I will enjoy the titles you offered.

I am always surprised at what a resource this site is for things non-music.

Thanks All

Several lps (and some CDs) are arriving to my home this days so, ... time to relax, open a nice bottle of wine, and let the blues masters play and sing.... cool!!!
