Perhaps I'm asking too much for a short piece that bills itself as a "file" but this is the kind of piece I'd generally tune out. Taylor's music is a constant background to Meister's chronicle of Koko Taylor's life, rather like an ad for a car. The straight-ahead bio doesn't do much either; I can get that quickly on the web somewhere.
A clip or two of Koko Taylor herself talking about where's she's at today would have really helped.
If this piece really wants to let the good-times roll á la Koko Taylor, we could hear perhaps a minute and a half of bio (with no background music), a minute of Taylor and the rest could be samples of her music.
I liked the Let the Good Times Roll extro.
