No, I can't do this (done top ten some time ago and that wasn't enough!). It would mean choosing only 5 artists so I'd cheat and have the 4-LP Story of the Blues by Paul Oliver and another compilation,probably the Chess Blues Sampler for the fifth just for variety- but choosing 5 as "top" would be too hard. Big Bill's Blues by Broonzy and the Leadbelly Library of Congress sessions and the complete Robert Johnson are easy but which Sonny and Brownie, which Fred McDowell, no , I surrender...
