Supergroup Radiohead are celebrating after their new fourth album reached number one in the US album charts.

Kid A, which also entered the UK chart at number one on Sunday, sold 207,000 copies to knock Let's Get Ready by rapper Mystikal off the top spot.

The chart-topping performance is a first for Oxford-based Radiohead who, despite widespread critical acclaim for their last two albums, only reached number 21 in 1997 with OK Computer.

The success of Kid A is all the more amazing as previews had been embargoed from radio airtime in the US until two weeks before its release and no videos or singles have so far been taken from it.

Meanwhile, the band led by Thom Yorke, plans to release another album recorded at the same time as Kid A, in the spring.

In the UK Kid A is outselling its nearest rival, Madonna's Music, despite relatively little promotion. The album's launch in Europe was hit by a technical glitch and 150,000 CDs sent to Germany, France, Spain, Portugal and the Netherlands had to be recalled

Most of the pre-release hype was carried out on the Internet with websites carrying tracks from the album. Kid A had its first public airing three weeks ago at the Zodiac nightclub in Cowley Road, Oxford, where the group played one of their first gigs.

The members of the band are former pupils of Abingdon School with hits like Creep, High and Dry and Karma Police.
