Heathen Chemistry is the fifth studio album by English rock band Oasis. It was released on 1 July 2002 by Big Brother Recordings. It is the first Oasis studio album recorded with guitarist Gem Archer and bassist Andy Bell, who both joined the band after the previous album Standing on the Shoulder of Giants had been completed. It is the last Oasis album to feature longtime drummer Alan White, who left in early 2004, due to what Noel Gallagher cited as White's lack of commitment to the band. Heathen Chemistry is notable for being the first Oasis album where members other than Noel Gallagher made a significant contribution to the songwriting, a trend which would continue in subsequent Oasis albums.
