Lib Ripper Mark Landvik opens up with an honest depiction of the stresses of producing at the highest level of filming backcountry freestyle snowboarding in the Snowboard Mag mini documentary “A Constant Evolution” playing now. It’s easy to forget that there are human beings behind the insane snowboard action you see passing in front of your eyes online and in videos all year long. This in depth snap shot humanizes the snow porn, reminding us all that a whole lot goes in to each amazing video and shot even for the super human Landvik and his storied career. The balance of the high highs, low lows and shifting landscapes (both physically and metaphorically) are all part of Landvik’s constant evolution through snowboarding, art and life.
