Solarference is Nick Janaway and Sarah Owen.
(...and is pronounced as in solar interference!)

Sarah Owen is a composer, sound artist, vocalist and workshop leader. She composes sounds for concerts, galleries, performances and out-doors events. She works alongside dancers, visual artists, storytellers, children and other people she meets. She draws from oral traditions, collaborations, conversations, environmental sounds, domestic sounds, accidental sounds, and sounds she can barely hear.

Nick Janaway is a sound designer, sound artist, singer and electronic musician. He makes sound for theatre pieces, short films, installations, and designs interactive sound software. He also writes songs which he performs and produces with a mixture of acoustic instruments and electronics.
