Flannery Brown, Armand Aromin and Benedict Gagliardi are musical symbionts that sprouted from a mutual loam. Soon after, they began to hum in sympathy, eventually buzz in synchrony, and now whomp with full-lunged abandon. Like a lively fungus on the branches of tradition, they nourish themselves on its ancient heartwood and burgeoning boughs-to-be. They are the Pope's frown, a wagon of porcupines, that cup of tea next to the worm bin. They sing for you and each other. As for the birds? Especially so.
