Like saxophones, jaw harps and accordions, the mere presence of a didgeridoo in a band is going to be a deal-breaker for some. But there's a lot more to the instrument than the flatulent drainpipe belches you might hear from buskers in Yoyogi Park. Wild Marmalade's Si Mullumby conjures percussive riffs and all manner of unorthodox sounds from his didge – so unorthodox, in fact, that the duo are constantly at pains to insist that there isn't any technological trickery going on under the covers. His co-conspirator, drummer Matt Goodwin, helps raise things from the merely groovy to downright infectious. Didgeridoos: not so rubbish after all.
