Christopher Andrew Joannou (born 10 November 1979) is an Australian musician best known as the bassist for the Newcastle-based alternative rock band Silverchair. He is a twin to sister Louise Kipa. He was the first of the three band members to cut his long hair short. Joannou was nicknamed 'Lumberjack' by Silverchair fans for his love of trees, and plaid shirts. His bandmate Ben Gillies taught him how to play bass guitar. Wikipedia
