COS

The Profile

COS is a Belgian progressive rock and jazz-fusion group from Brussels, formed in 1973 by composer-guitarist Daniel Schell out of the earlier band Classroom, featuring vocalist Pascale Son. Active through the late 1970s, COS crafted a Canterbury-influenced sound across albums including Postaeolian Train Robbery (1974), Viva Boma (1976), Babel (1978), and Swiss Chalet (1979).

Reviews and public sources note COS’s Canterbury-inflected progressive rock with jazz-fusion elements, wordless/scat vocals, and occasional oboe. The Postaeolian Train Robbery era lineup cited includes Pascale (vocals/oboe), Robert Dartsch (drums), Alain Goutier (bass), Charles Loos (piano), Steve Leduc (percussion), and Daniel Schell (guitar/flute). The Musea edition of the debut adds Classroom-era tracks recorded circa 1973.

A poetic, myth-tinged review lauds COS’s debut Postaeolian Train Robbery as a peak of their Canterbury-flavored jazz-prog. It highlights Pascale’s playful vocals and oboe, agile rhythms, and Charles Loos’s piano. The Musea edition’s Classroom-era tracks earn special praise. Overall sentiment is warmly appreciative and historically minded.
