Sonia Dada was an American rock, soul, and rhythm and blues band, formed in Chicago in 1990. Founding member Daniel Pritzker enlisted Michael Scott, Paris Delane, and Sam Hogan after hearing the latter three sing in a subway station. Sonia Dada has become a mainstay of the Chicago musical scene in the years since, incorporating elements of rock, soul, gospel, and funk. Since then, Sonia Dada has released four studio albums and a live album. Their 2004 release, Test Pattern, was released in a deluxe edition with a bonus DVD containing short films by Jeth Weinrich.
