So many artists in the field of electronic music choose to hide behind odd monikers as if to develop some kind of enigmatic persona to make them seem somehow more interesting. The real skill of course is to create some kind of mystery in the music that's created; some unique, subversive twist to separate the wheat from the chaff. Scotland's Boards Of Canada have achieved both feats and 'Geogaddi' prolongs the myth still further. Through 23 tracks in 66 minutes, the talented duo of Marcus Eoin and Michael Sandison have made one of the most captivating ambient/electronic albums ever. Short intervals separate the longer tracks and they neatly segue from one mood to another. For example towards the end of the album 'Dawn Chorus' sounds bright and hopeful but 'You Can Hear The Sky' counters the joy with a much more haunted feel. 'Gyroscope' is full of clipped beats and distorted child/child-like vocals and '1969' excels with its winning combination of swirling ambient effects and anguished vocal loops. There aren't too many artists around whose work is comparable to Boards Of Canada's compelling music, but those who enjoyed Radiohead's more considered moments on their last two albums might well appreciate 'Geogaddi'; in fact this is arguably a much more cohesive and seamless affair, minus the harsh, artful trickery of Thom Yorke and co. The word 'otherwordly' is too often used to describe music but in fact it's quite conceivable that this album was recorded by beings from another planet.
