Edge has been talking to Hot Press about the writing of 'Get On Your Boots'.

'We came up with 'Sexy Boots', and everyone got very excited by the idea and we pursued it, but in the end we just thought it was a bit limiting, and so we took it in another direction. That's the way it often happens with U2.'

As for the album itself, Niall Stokes, the Editor of Hot Press, who has followed the band from their earliest days, has got no doubts.

'No Line On The Horizon is a huge record, full of big songs, powerful riffs and superb musicianship. It's more musically diverse than any U2 album since Rattle And Hum, mixing hard rock, psychedelia, pop, electronica, dance, folk, country, spiritual music and orchestral shadings in what is a fantastically heady brew.'
