If it's twang it's our thang." So goes the motto of "Twang Sundays," which pretty much sums up this Sunday afternoon series of local music. Country, western, Americana, y'all-ternative, and rockabilly, as played by bands like the Pine Box Boys, the Robber Barons, and many more, comprise the fare. And Thee Parkside's patio offers benches and Ping-Pong for those who take their Buck Owens with a spoonful of midday sun. Ease into your Sunday for the low, low price of $0.
