This week on Retrofit is Blues Covers.

We know that Led Zeppelin, the Rolling Stones, Jack White and so many others were profoundly influenced by early American blues that sprang up from the Mississippi delta, the Chicago night spots, even a recording studio that was a side project of a Wisconsin furniture enterprise. Hear the originals and the updates, the similarities, the differences, and what it's like to have a "fore day creep" or even a "black cat moan."  

Blues Covers on Retrofit, 5 p.m. Saturday, Feb. 28. Have mercy.
