Chambers originally wanted to learn to play the piano, but his parents could not afford to buy one. So instead he saved money from his Saturday job, stacking shelves at the local grocers, and at the age of 14 bought his first drum kit. 
He moved to his wife's native Australia, was involved in session drumming as well as recording and touring with the band Dragon (late 1983 to mid 1985). He was featured on the Dragon albums Body And The Beat (1984) and the live album and live home video Live One (1985). He is also featured in the promotional video clips for the songs "Wilderworld", "Cry", "Magic" and "Rain".
