Louisiana-bred, Brooklyn-based recording artist Julianna Barwick crafts ethereal, largely wordless soundscapes, all of which are built around multiple loops and layers of her angelic voice. Barwick, who credits a rural, church choir upbringing for her unique sound, begins most tracks with a single phrase or refrain, then uses a loop station and the occasional piano or percussive instrument to build the song into a swirling mass of lush, ambient folk.

Sarah Hopkins is a unique Australian composer-performer, highly acclaimed for her visionary music and inspiring performances for cello, harmonic overtone singing, handbells, choir and the celestial Harmonic Whirlies of her own creation. With a strong background and training in classical music, over the years she has moved into the realm of holistic music and developed a very distinctive compositional voice.
