TBT: Sonny Boy Williamson, "Nine Below Zero".

It hasn't quite made it to nine below zero here in New York yet--well, maybe on the Centigrade scale--but it's sure felt like a shock after our mostly balmy December. Still, it's an appropriate time for this blues, led and sung by the greatest of blues harmonicists, Sonny Boy Williamson. Born a sharecropper's son in Mississippi, like many great blues artists he found his way to Chicago and to Leonard Chess, for whose Chess label he recorded.
