Re-Hash is the 1st track on the Gorillaz' 2001 album Gorillaz. It is described in the Rise of the Ogre as 'a gloriously upbeat opener to the album'.

The song was written by 2D and Murdoc. Murdoc wrote random phrases on magnets and 2D threw them at a frigde. They kept whatever phrases stuck in the refrigerator. 2D was coached by Damon Albarn to sing more confidently in this track and, as stated by Russel, 'lose the thin reedy sound of the early rehearsals'. Backing vocals were provided by Noodle as well as Cibo Matto's Miho Hatori. For the bass sound, Murdoc placed his amp underwater, in a fish tank on the floor above. Then they held a microphone up to the ceiling below and recorded the bassline. As he stated, that's why the bass in Re-Hash is 'all muffled and well dubby'. 2D added a broken sitar sound to the track to give it that 'extra dash of weirdness'.
