i just saw this splendid 1968 documentary "the blues accordin' to lightnin' hopkins" by les blank (if you haven't seen it, i highly recommend it. i don't really listen to lightnin' that much, but the film is beautiful). there was a scene with lightnin' playing on a barbecue and he was accompanied by something i've never seen before: a guy wearing a rippled metal vest covering his full torso, he was playing some awesome rhythms on it. like a vest, it was wrapped around his body, so it never gets in the way. is that often seen? i'd really like to get my hands on one of these, but don't know the name. it could also be possible to build one myself, but i should know about what type of metal to use, what gets you the nicest sound. thanks in advance
