The Allen Brothers. Lee and Austin from Chattanooga Tenn. (the "Chattanooga Boys"). Guitar/Tenor Banjo brother duet with lots of kazoo who recorded in the late '20's and early '30's. These guys were the DEFINITIVE fusion of Blues and Old-Time Country. Had big hits with "Chattanooga Mama" and "Jake Walk Blues" but became infuriated with their record company when they were marketed in the "race"(i.e. Black) category (the Allens were White Southerners). Their complete recorded works are available in 3 volumes from Document records. I've never met anyone who heard them that didn't think they were great.
