For the past 15 years Australian duo Clocked Out (Erik Griswold and Vanessa Tomlinson) have explored the possibilities of prepared piano, percussion, found objects and toy instruments. Their work combines experimental, improvised and world music traditions, taking inspiration from such diverse sources as Feldman, Riley, Oliveros, Sun Ra and Sichuan Opera.
