Today we celebrate the birthdate of Robert Johnson - Father of the Delta Blues. His recordings of "Cross Road Blues", "Love in Vain", "Sweet Home Chicago" and others became blues blueprints influencing everyone from Muddy Waters to The Rolling Stones to Eric Clapton.

Leave your suggestion in the comments below and we'll spin a set this morning.
