In honor of Movember, we’re teaming with Ultimate Classic Rock and Loudwire to take a look a several notable rock mustaches, beginning with the musician on the left. This former Birthday Party frontman is best known as the singer of another Aussie group -- one that formed in 1983 and has spent nearly 20 years churning out a very distinctly dark-sounding version of post-punk and alt-rock music, releasing a total of 13 studio albums, including their best seller to date, 1996's 'Murder Ballads.' Since 2006, he's also fronted a side project called Grinderman.
