The ambitions of the group are drawn on the album cover: surf the heights of pop (frosted). The combo of Oxford led by Johnny Greenwood and Tom Yorke is a priori experienced enough to achieve his ends. With The Bends and OK Computer Radiohead had already gained altitude, leaving the competition pinned down. The public does not make a mistake, "OK Computer" was voted best album of all time by readers of a famous British music weekly, before the excellent Beatles Revolver. The critical and public success of this album reward the requirement of the group, and encourages her to experiment more. This disc marks a transition: the machines (and experimentation) are requested. By summoning them to dress "OK Computer", the group discovers that they can be useful to see its frosted pop dreams realized, and thus are used for all of Kid A, to the point that the guitars are reduced to playing second fiddle. On leaving the disk baffles a large number of fans accustomed to the sound of grunge "Creep" or sprinkled electro pop of "OK Computer", but attracted many music lovers converted to electronic music since the mid-90s, thus finding a deserved hearing. Coherent, extreme, Siberian, this album is a breathtaking beauty
