You gotta have Howlin Wolf and Muddy Waters :) I got a couple of recent "best ofs", both double CDs, no idea what they're called, but they got everything what you need :lol:
And I didn't notice John Lee Hooker in the list above?
And check out a current English chap called Ian Siegal - especially "Swagger" and "Meat and Potatos", but anything by him that you can lay your paws on...
