If you are fascinated by American roots music from the late 20' to early 30's this is your special.
I have a technical interest in early electrical sound recording and this PBS special gave me many images of the early recording equipment which I have never seen before. The music was good too although not my primary reason for buying this PBS special.
A masterwork containing extraordinary treasures of sound, images, and troves of information. There are wonderful surprises in store for the viewer no matter how well informed you might be on American Blues and Jazz.
