Formed in Berlin in 1968, Birth Control were known for a progressive hard rock sound fused will elements of jazz, psychedelia and Krautrock. A surreal concept work from 1976 recorded by legendary producer Conny Plank, Backdoor Possibilities arguably marked their final creative peak, combining rock, jazz and avant-garde stylings with intricate polyrhythmic textures and lyrical nods to Faust and Odysseus. This expanded double disc edition has been remastered by Zeus B. Held and features three bonus live tracks recorded in Korbach on 1 May 1977, as well as a bonus live disc taped at the famous Sartory Saal in Cologne on 24 September 1976.
"Possibilities" is an intimate documentary about Herbie Hancock and his in-studio collaborations with a dozen formidable pop recording artists, collaborations that explore the unexpected, like jazz improvisations. The film is also about how Herbie's unique world view shapes a creative environment that encourages artists to step outside the velvet prison of easy expectations. "The hip stuff," Herbie tells Trey Anastasio, in a scene from the film, "is outside the comfort zone." "Possibilities" follows Herbie over a year and a half collaborating with musical icons Carlos Santana, Sting, Angelique Kidjo, Annie Lennox and Paul Simon, young superstars Christina Aguilera, John Mayer, Trey Anastasio and Jonny Lang and newcomers Joss Stone, Raul Midon, Damien Rice and Lisa Hannigan. The film also puts Herbie's latest work in the context of his extraordinary musical career, and includes rarely seen archival footage of Herbie with the Miles Davis Quintet in 1962; Herbie leading his Headhunters.
