There are at least six bands called Cocoon: 1. Cocoon is a two-piece French band formed in 2006 by Mark Daumail (born 1984, composition, lead vocals, acoustic guitar, ukelele, banjo, beatbox, etc.) and Morgane Imbeaud (born 1987, vocal harmonies, keyboards, arrangements). "I wanted it to be a male-female duet. A duo like the White Stripes are in rock — we wanted to be the equivalent in folk music," Daumail says. Their songs are entirely sung in English.
