Speaking to nme.com backstage following Radiohead's performance at Scott Walker's Meltdown Festival (July 1), bassist Colin Greenwood revealed that the record will feature the tracks 'Optimistic', 'The National Anthem', 'Everything In Its Right Place', 'Kid A', 'How To Disappear Completely And Never Be Found' and 'Motion Picture Soundtrack', as well as between four and six other new tracks, which are rumoured to include ‘In Limbo’, ‘Idioteque’, ‘Egyptian Song’ and ‘Morning Bell’.

Greenwood also revealed that two other songs, 'Knives Out' and 'Dollars and Cents', which have been played throughout the band's current European tour, will not feature on the new album.

He added: "We've mastered the first record and it should be out at the end of September. We've done lots more recordings and we're trying to find the right way to release more of the songs...we want to find a way of releasing the other songs we've recorded, not just on EPs, and put it together as another piece of work...we've got lots of other songs that we want to release sooner rather than later.

"We didn't want to do a too long record, didn't want to do a double album because that is very boring...This record is a not a definitive statement."

Greenwood said that it was unclear what would happen to the new recordings, but revealed the band wanted to play more of their songs live via the Radiohead website, www.radiohead.com, claiming their previous webcasts to be "one of the most exciting things this year for us".

When questioned about industry rumours that the album title is 'Kid A', he said: "That's a very good guess, yes! I think that's pretty good! I think so, yeah."

Greenwood told nme.com that the band had been "very scared" about playing in the UK again, adding that the reason they decided to play this gig was because of their love of Meltdown curator Scott Walker. He continued: "It was the reason we did this tour again, we had such a stressful time with the last tour. We've all been so influenced and inspired by the man and it was great to meet him and play here.

"Everyone's very happy and relieved that we've managed to play tonight. We were all very scared because it was very important to us. It didn't make any sense to do this show in terms of bullshit commercial reasons, but the chance to meet the man is great. The idea that you can play these things and be part of local music festivals in the summer rather than some big rock tour appeals to us, to be part of other people's music culture."

Radiohead's next UK dates are also in September, when they play Newport Tredgar House (September 1-2), London Hackney Victoria Park (23-25), Glasgow Green (28-29) and Warrington Victoria Park (October 1-3).
