As far as more recent recommendations, if you are into the mouth harp, William Clarke was a fantastic harmonica player on the LA circuit (who unfortunately passed away somewhat recently). In particular, I recommend Serious Intentions and Blowin Like Hell (both on Alligator Records). Also, although they've gotten some coverage in high end magazines, the North Mississippi All Stars are probably the most fun blues band I've heard in the last few years (both Shake Hands with Shorty and Highway 51 on Tone-Cool records are a blast). Finally, if you are looking for "audiophile quality" recordings, any blues on Audioquest (particularly Robert Lucas) and Analogue Productions (Jimmy D. Lane, Big Daddy Hypolite) would be worth a look.
