Video by the author. Photo by Jade Katz.A few weeks ago, Lower East Side legend Clayton Patterson introduced my friend Jade Katz and me to Axel, a blood artist and jewelry designer. For years, Axel has been using his own blood as paint to create art. He learned the skill at Salvador Dalí's dinner parties, where guests played rounds of exquisite corpse. The game taught Axel that he could paint with his own blood, and he's used his blood as paint ever since. His work has earned him the reputation of being a (literal) bloody genius, and he showed us why when he gave us a private tour of his latest show at Art on A.@RedAlurk
