RD King is a Boston-based composer and acoustic guitarist and the winner of the 2017 Canadian Guitar Festival’s International Fingerstyle Guitar Competition. King’s audiences describe his music as passionate, powerful, deeply memorable, and — at times — extraordinary. His debut album, “vs. Self,” was released in 2017. Opening for RD is Acton-based Walter & The Night Owls, an alternative-folk music quartet that has been making waves in the independent Boston music scene. Combining acoustic guitar, violin, and cello with soft vocal harmonies they create a sound all their own. Music from their initial EP has been featured in commercials and films, and has been licensed for use on MTV2 network specials along with other international media outlets. Their debut album, “Living in all Directions,” was released in 2015.
