Hi. I've been wanting to get to know blues better and I would like to get to know the most influential blues people. I don't mind the bass at all, I just want to get to know the most important people to the development of the style. I am already familiar with the Robert Johnson recordings. I would like to get some recommendations of people that started to play up until 59, not after. If you could tell me what is the subgenre that they are usually considered to be it would be nice. Album recommendations would be nice to, instead of only the names of the players. Remember, I want stuff that was influential and widely recognized, not necesarilty something you like or that "is great music". Thanks in advance.
