As a performer, Frédéric Roverselli surfaced in the late '90s as the bassist of Montreal avant-prog group Papa Boa. But he was shortly known as a composer of electro-acoustic music. Since the early '90s, he works as a sound designer on corporate and artistic projects with a focus on new audio-visual digital technologies. Roverselli studied music in college and electro-acoustic composition at the undergraduate level at the Université de Montréal from 1988 to 1991. During the second half of the 1980s, he was active as bassist in a number of local rock bands, including Sneakers and Hollywood Mufflers; the latter also featured young drummer André "Dédé" Fortin who later formed Les Colocs, one of Quebec's leading groups of the 1990s. But, as he finished his undergraduate studies, Roverselli's interests shifted from performance to sound craft. Together with guitarist Bernard Falaise and drummer Rémi Leclerc he formed Papa Boa in 1991, first thought of as a studio laboratory group. He wrote a few electro-acoustic pieces in the early '90s, some of which were performed and a couple included on compilation CDs. He also took part in the Orchestre-Vélo, an electro-acoustic ensemble/installation involving bicycles equipped with noise-makers and loudspeakers. But he quickly withdrew from academia and began recording soundtracks and sound design for TV spots, corporate videos, film documentaries, and video games. In 1995, he created Espace Meta, an interactive CD-ROM on urban sound environment. With Papa Boa, Roverselli devised music for interactive works and explored the use of recorded improvisations in studio compositions, but by 1999 the group had become a performing unit with a repertoire and an album, Tête à Queue, released on Ambiances Magnétiques. This return to live work prompted him to write songs he began to perform solo in 2001 under the moniker Frek. ~ François Couture, All Music Guide
