The Atlantic Harmony Brigade is weekend of wall-to-wall, chord cracking, barbershop quartet singing. If you are a fast learning, experienced quartet man, and you yearn for good, challenging quartetting with a network of solid, like-minded, and accomplished quartet men, the Atlantic Harmony Brigade may be for you.
The AHB's new video gives a good overview of what the Brigade experience is like. You can find more Brigade opportunities at harmonybrigade.org.
