Willy Nilly plays an eclectic mix of indie/folk rock music that taps into a variety of influences. The band's sound is uniquely familiar, combining elements of classic rock, 2000s indie rock and country/folk singer-songwriter in their lyrically driven songwriting. The band's performance has a laid back feel that still remains upbeat, and is non-abrasive enough to be enjoyed as background music for the less keen listener.
