Guy Rupert Berryman (born 12 April 1978) is the bassist and member of the group Coldplay.
As Berryman started an engineering degree at University College London, he somehow heard rough versions of Chris Martin's songs, and, drunkenly, approached him in the student bar demanding to be admitted into the "band", which then consisted of Chris Martin and his best friend Jonny Buckland. Soon after, he dropped out of his engineering course and switched to a seven-year architecture program. He dropped out of his architecture degree after one year to focus on playing bass with Coldplay. While his bandmates were still continuing their degrees, Berryman worked as a barman in a local London pub.
During the Twisted Logic Tour for the promotion of Coldplay's third album, X&Y, Berryman took candid pictures of the band with disposable cameras and threw them to the audience.
