Sonia Dada are a Chicago rock/soul/rhythm and blues band, which tours with anywhere from 6 to 8 members. The band formed in 1990, when founding member Dan Pritzker heard three future members (Michael Scott, Paris Delane, and Sam Hogan) singing in a subway station. Sonia has become a mainstay of the Chicago musical scene in the years since, incorporating elements of rock, soul, gospel, and funk. Their 1992 debut album, Sonia Dada, produced a minor radio hit, "You Don't Treat Me No Good", and sold more than 100,000 copies.
