The Cat Box Quartet are Copenhagen-based Marc Kellaway and an assortment of musicians. 'Running Uphill' is remarkable not just for being the first entirely instrumental release on Radio Khartoum but for the actual choice of instruments used which include thumb piano, viola da gamba and melodica. Such subversion could have led to a triumph of artistic endeavour over experimentation but - this being a Radio Khartoum release - the music provided is peppered with melody, albeit of the off-kilter, obscure variety. This is the kind of record where a title like 'Slowly Loading Paper' is a description of what exactly is happening. Cunningly, 'Running Uphill' begins and ends with a funereal tone but there's much eclectic joy to be had in between.
