One afternoon, I set up my kit and taped a drumstick to my amputated arm

The transformer exploded a few feet from where I was standing. One moment I was on the roof of a restaurant kitchen in Atlanta, cleaning exhaust vents. The next, I was on the ground, my body seizing and burned.

Before that day, music had been the centre of my life. My father was a well-known guitarist in Australia and I grew up watching him play. When I was 14 my parents bought me a drum kit for Christmas. I fell in love immediately. By 22, I was playing in two bands – one metal, one reggae – and preparing to audition for the Atlanta Institute of Music. Then I was electrocuted.
