From the humble garage-days back in 1994 to the present fast changing times, Rock Machine has always followed one basic principle: Having fun behind the bars. Sure there are months in front of the computer, sure there are miles & miles on the jetplanes, sure they spent countless of hours by refining even the smallest frame details.
