Song X is a collaborative album by Ornette Coleman with guitarist Pat Metheny, recorded in December 1985 and released in 1986 on Geffen Records. The project arose from mutual admiration between the two musicians and their desire to explore the harmolodic language.
The recording sessions took place at Power Station Studios in New York, featuring Charlie Haden on double bass, Jack DeJohnette on drums, and Denardo Coleman on percussion. The music alternates between structured compositions and passages of free improvisation.
The album was nominated for a Grammy Award and received praise for its bold integration of free jazz with contemporary jazz and rock. Song X is considered a unique dialogue between two generations of jazz innovators.
