Undiscovered blues gems.....

Peter Green The Splinter Group. I love this Cd and they also have a Double Cd version of two disc's one The Robert Johnson Songbook along with HotFoot Powder both doing all of Robert Johnson's songs. Some are guitar alone but most of them are with the band. Worth checking out. Pass on Time Travelers and Destiny though.

Not really recent, but blues piano is a "sub genre" you may have missed. Try anything from Professor Longhair. Also James Booker's "Lost Paramount Tapes" is an absolutely great introduction to this music.
