As Fog, Andrew Broder constructs fragile soundscapes using everything from his beloved turntables to bird whistles and music box tunes. There’s something Heath Robinson-like about his twittering creations, which use hip hop as their base but defy all attempts at categorisation and recall artists as diverse as Keith Jarrett, DoseOne and Smog. Broder has described his second LP as “an urban vaudevillian symphony”, but although a barbershop quartet looms briefly in “I Call This Song Old Tyme Dudes”, Ether Teeth is a thoroughly (post-) modern affair.
