The Temper Trap formed as an indie pop band in 2005. Indonesian-born Dougy Mandagi was a busker in Melbourne in 1999 when he met Jonathon Aherne Aherne wanted to learn to play guitar. Six years later, Mandagi met Toby Dundas while both worked in a clothing store. In 2005, they decided to form a band with Mandagi on vocals and guitars and Dundas on drums. Mandagi contacted Aherne and convinced him to join on bass guitar. The group was named The Temper Trap after their first choice, Temper Temper, was rejected due to its use by a United States band. The Temper Trap rehearsed with a variety of second guitarists before Dundas recommended his former Geelong Grammar schoolmate, Lorenzo Sillitto on lead guitar. The group performed at St Jerome's Laneway Festival in March 2006.
