After studying percussion in his home city with the late Richard Smith, Askill traveled to New York to study under Jean Batigne as the recipient of an international fellowship from the Australian council. In 1992, Askill served as the musical adviser to Graeme Murphy's production, #Synergy With Synergy, performed by the Sydney Dance Company. Askill and Murphy renewed their collaboration when Askill served as musical director and composer for Murphy's production, #Free Radicals, in 1997.
Askill has been featured on several albums. Australian Percussion, released in 1991, featured his interpretations of original works and pieces by other Australian composers. Askill recorded his 1995 album, Fata Mogana, with Omar Faruk Tekbilek, a Turkish flute, reeds, lutes and percussion player he met at an Australian broadcasting studio. Askill produced an album, Tango, for the Daniel Binelli Septet in 1996 and an album of Heinrich Schutz motet settings, Der Schwanengesang, recorded at the Sydney Opera House with the Song Company. Askill served as musical director of the Sydney Dance Company's 1998 production, Salome. The solo Rhythm in the Abstract followed in 2000. ~ Craig Harris, Rovi
