Radiohead and Red Hot Chili Peppers are battling it out for the number one spot on the Official Albums Chart.
Radiohead's A Moon Shaped Pool was released physically last Friday and sold more than 32,000 copies.
After factoring in digital purchases, 34,000 combined chart sales have been logged, according to the Official Albums Chart Update.
