Amanda Sudano and Abner Ramirez are the sound of new Nashville — that is, both musically trained since childhood, Ramirez through school in his native Jacksonville, Florida, and Sudano by her mother, Donna Summer. Both transplants to the country-music mecca, they met after a Sunday church service, and that was that. The duo that now goes by Johnnyswim was born. Taking their name from Johnny, a cat that was once chased into a river by Ramirez’s dog, the band makes jubilant folk, blues, and pop. Their earthy sound, replete with hand claps and knee slaps heard on nearly every track, is lent a somehow audible element of authenticity, having actually been produced below the Mason-Dixon line (and not, say, in Brooklyn). Last month, they released A Johnnyswim Christmas, and we’re still grateful for the batch of non-nauseating holiday tracks. Catch them up North tonight and tomorrow.
