Blues from the 50s/60s/70s

Crem1 I understand, is impossible to ask for some references with "just" an email right?
Chashmal, english is not my first lenguage and I do what I can, sorry.
Thanks Rushton for the long list and the time you spend typing. I have some of the LPs that you listed and will keep an eye on the rest.

Thanks for the support, honestly dont understand why those first two answers , is easiest just not to post.
I was just asking for some advice thats all, I do not have the intention or the money to steel those "marvellous treasures" to the gods of music like Robert Plant (by the way I love Led Zep and have all their recordings).All that I want to add to my collection some blues LPs from great artist and if its possible with nice recordings. Hope this time Crem1 could understand and post some advice and Chasmal....sorry for my terrible english ... again.

Now I have a lot of homework!!!(lol).
Is good to know that this thread will be helpfull for others also.
Thanks to all.

Mm2550, for me Lps sounds way much better than CDs, is fascinating how each LP sounds different from the other, more obvious when they were recorded in the 60s or 70s, they have a lot more presence and realism than CDs, but thats only my opinion of course.
Until now I have my music collection (about 1,000 CDs) stored in my computer under FLAC format and I played with a very good sound system. About a month ago I decided to return to vinil (Im getting older), found a very good turtable with a great cartridge, an almost new collection of records of the 70s and ... here I am, enjoying a lot rediscovering the analog sound !!!

Thanks again to all for your great help. Time for me to enjoy the blues!

yes POlk432, I love guitar and thanks for the recomendation, I will some of his LPs for shure!

Crem1, no, I dont have the intention to spend lots of money in originals and/or very difficult to find presings, thats not the idea and I dont undertsand why you assume that, I was only asking for some names and recordings that people consider must be part of a nice collection of blues, I thought that I can do it all with LPs but because your last post, I must assume that for early recordings will be easier to go with CDs, and maybe LPs just for late 60's and 70's (found -and start to buy- in Ebay several of the artists/recordings that people gave me here for rasonable prices); thats the kind of advice that I was looking for ,nothing else, and looks like everybody understands exactly my question. Thanks for your last reply.

Mothra, must be interesting to explore that also, would you give me some names that you consider I can find in CDs? thanks in advance

Thanks Robdoorack for that information, Im sure will be usefull for all.

Thnaks Crem1 for the imput.

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.

Wow!! I will need 5 lifes to read all that !!!!

Now we have a very usefull information for us and others with same interest in blues.
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!!!
This is great, thanks to all. Jorge
