Possibilities is the forty-fifth stuio album by American jazz musician and pianist Herbie Hancock, released in 2005 (see 2005 in music). The album features a variety of guest musicians such as John Mayer and Carlos Santana. It also earned him two Grammy Award nominations in 2006: "Best Pop Collaboration with Vocals" for "A Song for You" (shared with pop singer Christina Aguilera) and "Best Pop Instrumental Performance" for "Gelo na Montanha" (shared with rock singer-guitarist Trey Anastasio). A motion picture called "Herbie Hancock:Possibilities" depicts the recording of this album in many different discussions and performances with the collaborating artists.
