Julia Parker, one of the first employees of Indigo is often fond of making profound philosphical points. As summer comes upon us for another year I remember her passion for an upbeat album called Two Shoes by the Cat Empire, a Melbourne (AUS) based band, and her particular habit of raving about the fifth track. She said that everyone needed a track number 5 – a summer track that makes you jolly. I’m intrigued – what are peope’s track number 5’s? What should we be playing in the office this summer?
