This eight-minute musical composition arose in a highly innovative context created and implemented by the composer. Previous experience with collaboration between performers and composers had led to the idea of bringing together several virtuoso ensembles to create a new kind of orchestra. This would address several desires, including the creation of large-scale work for performers whose main activity is contemporary music (which is not the case with established orchestras), the ability to execute exacting and complex rhythms in a large ensemble, the building of collegiality between similar-minded artists, and the expansion beyond familiar territory for performers, composers and audiences. The Sixpack Symphony was the result of Davidson bringing together six ensembles: The Brodsky Quartet (London), Topology (Brisbane), Clocked Out (Brisbane), Continuum (Sydney), Wood (Perth) and David Chesworth Ensemble (Melbourne). Each ensemble contributed a piece, and the contribution of Topology was Davidson's Round Roads. The work portrays Canberra from the perspective of the composer returning there as an adult, having spent his childhood years in the city. It has been rescored several times, including for Topology alone (soprano saxophone, violin, viola, double bass, piano), for Topology with drums, for Topology with soprano Katie Noonan, for Topology and Misinterprotato (a jazz piano trio), for the Melbourne ensemble Six Degrees (soprano, violin, viola, electric guitar, percussion, piano) and for piano duet.
