I suppose it depends on how your taste runs Spike. Personally, while I appreciate the music of the 20's and 30's I have to admit that I find it difficult listening for extended periods, mostly because of the recording/sound quality, which is due to the era in which it was produced.
Have you ever heard Susan Tedeschi? She is a great singer / guitarist along the lines perhaps of Janis Joplin, with far better vocal capabilities. I actually had the pleasure of seeing her in a TINY lounge in a restaraunt in Marshfield, MA when she was still basically on the club scene. Shemeka(sp?) Copeland is also a fantastic vocalist.
There is another band out of Rhode Island called Roomful of Blues. Over the years they have featured guitarists such as Ronnie Earl and I believe Duke Robbilard. They have many cd's out as they have recorded 30+ years, and feature a great horn section, which personally, is my favortie shade of the blues, bands, like them, or B.B. King's band, in which horns play a prominenet role.
