Spring Heel Jack

English duo Spring Heel Jack are perhaps best known for releasing a trio of "intelligent" drum n bass albums during the '90s, while dabbling with mainstream music as producer for Betty Boo and collaboratoring with Everything But The Girl. More recently their albums for the Thirsty Ear label have seen the duo move away from drum n bass to collaborate with improvisors from the United States and Europe, including saxophonist Evan Parker, bassist William Parker, tombonist Paul Rutherford, drummer Han Bennink and pianist Matthew Shipp.
