Texas Soww with his New Washboard Rhythm Kings

"Mechanical Jazz" band playing the Monterey Mechanical Jazz Festival in the 1970 sci-fi novel After Things Fell Apart. by Ron Goulart.

"That big sensual looking spade on platform six is Texas Soww with his New Washboard Rhythm Kings. I'm not sure why they call themselves that. I suppose it has something to do with all the laundromat machines he uses in his act. The guy sitting on the mangle and playing the mouth harp is new to me. Hey, look, Texas is stripping and throwing his clothes in that washing machine. See, he can play the trumpet at the same time. That would be interesting in bed, wouldn't it?"
