Built around male/female vocals and guitar/piano/violin instrumentation, the band's debut album fit nicely within the indie folk wave of early Fleet Foxes and Mumford & Sons. With Until I Live, the band took a step away from the folk niche but still emphasized their core elements in a much more expansive and energetic album. With Places, released in September of 2017, the band continued evolving in a similar direction. Places incorporates distinctive pop, electronic, and rock elements but blends them with Parks' signature songwriting and the warmth of the group's well-loved vocal harmonies and classical instrumentation.
The National Parks’ earliest touring was done as a three-piece but has grown as the music has evolved. A wide cast of musicians have joined as touring members of the band but by 2015 the group had settled into a consistent five-piece setup with Brady Parks being joined by Sydney Macfarlane (the only other original member) on keys and vocals, John Hancock on electric guitar, Cam Brannelly on drums, and Megan Parks on violin. In February/March 2018, The National Parks will be joining Ron Pope as direct support on his “The Dancing Days World Tour.”
