O.A.R., the prolific band behind hits such as “That Was a Crazy Game of Poker” and “Shattered,” takes its jam-centric show on the road in support of its upcoming new album, King. From humble beginnings to sold-out Madison Square Garden shows, O.A.R. has garnered an armada of fans with its high-endurance live shows and infectious, non-sea-based shanties, sometimes stretching two-minute ditties into 20-minute opuses. Sharing the spotlight, SOJA and singer Kelley James decorate eardrums with ragamuffin melodies.
