"Castellorizon" is the opening track on David Gilmour's third solo album, On an Island.[1] It is an instrumental guitar solo, which starts off with an overture of various sounds from other tracks of the album before the guitar is introduced. The song is based on a night Gilmour spent on the Greek island of Kastellorizo. It segues into "On an Island", the title track. The song received a nomination for Best Rock Instrumental Performance at the 49th Grammy Awards. The song was nominated for the same Grammy Award again at the 51st Grammy Awards for a performance from Gilmour's Live in Gdańsk album.
