WWOZ will be signing off at midnight tonight from their French Market studio, which was shuttered up and locked down already Wednesday night when I closed my own show, and will stay off the airwaves till Gustav passes. They've moved one of their mobile broadcast trucks to the Louisiana Public Broadcasting building in Baton Rouge as a failsafe measure to get back on the air ASAP if things... you know. I tuned into the Problem Child's regular Friday afternoon blues set today... and I'll give her Mac Rebennack's "Storm Warning," because it's her theme song, but I got the barometric creeps as I heard song after foreboding song. "Mississippi Heavy Water Blues?" Spencer Bohren's post-K lament "Long Black Line"? And a track I didn't know, with howling-wind sound effects under the lyrics "There's a lady in the Gulf/ who you don't want to know?" Jeez. At least this one doesn't have the euphony of the name "Katrina," whose easy meter spawned an unfortunately large catalog of musical paeans, most using the gimme rhyme "FEMA." "Gustav" just rhymes with "buzz off." EDIT: As of Saturday afternoon, 'OZ was broadcasting pre-recorded shows on CD from Lafayette on 90.7 FM. All the better for an evacuation soundtrack.
