Walk Off the Earth (Sarah Blackwood, Joel Cassady, Gianni Luminati, Ryan Marshall and Mike Taylor) is ready to restore your faith in New York City with a feel-good ode to the Big Apple titled "Fifth Avenue," premiering exclusively on Billboard today (Sept. 27). Exploring the wonders and challenges of living in the concrete jungle, the upbeat, New York-inspired tune narrates both the coming of age and the constant epiphanies brought by the chaotic -- but endlessly inspiring -- life in the city.
