Lisa and Danielle formed REXDuo when they got tired of never singing together even though they were part of the same new music group, Lunar Ensemble, for six years. They exist to sing badass music for two sopranos, either written for them or wrangled by them.
Their first major collaboration with a composer is Apocalypse by James Young, which is a full-length work for two sopranos, drumset and electronics,
​to poetry of Anthony Madrid.
