One band that I've been lisening to a lot recently is the threesome 'HowellDevine' (Joshua Howell - Harp/Guitar, Pete Devine - Drums, and Joe Kyle Jr. - Bass). They play a style of blues that's hard to pigeon hole so let your ears decide;
Reading "Blues All Day Long - the Jimmy Rogers Story - the accounting of this album made me check it out and download it. Backed by Rod Piazza and his band the Mighty Flyers, it is a great collection of vintage Jimy Rogers sounds with wicked harp backing by Rod Piazza (and great keyboard by his wife Honey). Worth a check IMHO
