Finnish singer Ari Koivunen (Amoral) took part in a charity concert called Millstones 2010  on October 13 in Helsinki. The event’s goal was to raise awareness and funds for treatment for persons suffering from intoxicant addiction.

Fan-filmed video footage of Ari performing cover versions of Dio’s “Don’t Talk To Streangers” and Deep Purple’s “Smoke On The Water” (with Koivunen on drums and vocals!) can be viewed below.
