Honestly, if you weren't keeping track of his footage, would you even know who he was? Not his fault, but his name is like a half dozen other pros.
myself i think i mostly remember him from of how strongly he was introduced on organika a while back, i mean they named an entire video after him - "zach [lyons] and walker's concrete jungle", which they released just as zach and walker ryan got on at the same time. that video was so sick at the time, with one of zach's funkiest sections (to me, on par with his pitcrew stuff) complemented by walker ryan's tech shit (skating to peter bjorn & john...) and a rad montage in between featuring quim and all. the length was the perfect format so you could watch it before skating too. bought many organikas after that (the decks were pretty sick) and actually just recently got to cope the dvd, seven years late, local shop had it stored away in a random shoe box.
ever since watching that organika vid i hadn't watched a walker ryan part again i don't think (always thought zach lyons was cooler... haha), but i've always recognized his name. and zach keeps coming to mind everytime walker ryan gets mentioned although they skate nothing alike, just because of that video and it's been almost a decade
