For almost as long as they’ve been married (26 years) Brett and Rennie have written songs together (Brett, music; Rennie, words). Their finished work is never fully one or the other’s, but lives in unseen space between them. William Burroughs claimed he walked busy streets without being seen, simply by seeing everyone else first. This is similar to the Sparks’ approach to songwriting and why Rennie embraces her power to vanish. You have to willingly disappear in order to write lyrics for someone else’s voice, or to write music for someone else’s words. Invisible songwriters are happiest when their songs outshine them, leaving their creators unseen in the dust.
