The hip-hop and art communities lost a legend last week when Wayne “Stay High 149” Roberts died at Calvary Hospital in the Bronx at the age of 61. Roberts’ sister, Pauline Noble, said he died of complications from liver disease.

As with the majority of semi-public to public figure deaths, those who were friends with or influenced by Roberts took to Twitter give their thoughts on the legend.

“Rest in power to one of NYC’s graffiti legends, Wayne ‘Stay High 149’ Roberts,” said DJ Clark Kent. “Truly a king.”

“RIP Stay High 149,” tweeted journalist and hip-hop historian Davey D. “A true legend and pioneer.”

Even artist Shepard Fairey paid tribute to Roberts on his website. “Stay High was a significant pioneer of graffiti culture not only in his proliferation, but also in his use of the smoking saint character as a supplement to his tag,” said Fairey in a statement. “I met Stay High a couple of times and he was very cool and funny. He will be missed, but his influence will endure.”

Born in Emporia, Va., in 1950, Roberts moved with his family up north to Harlem when he was 7. Almost a decade later, his family moved north again, but this time, it was to the Bronx, where the legend began to take shape. Given the nickname “Stay High” by a friend because of his love for marijuana, Roberts took that name to new heights after noticing tags in the subway while working as a messenger on Wall Street. He started writing his name all along the Grand Concourse in the Bronx and eventually made his way to the subways, trains and buildings as well.

“Stay High” wasn’t Roberts’ only contribution to the scene and the culture. Roberts is also known for his famous “Voice of the Ghetto” tag, as well as the famous “Smoker,” a stick figure from the old television show “The Saint” turned around and smoking a joint.

Roberts disappeared from the scene for 25 years but resurfaced in the year 2000 at an art exhibition in Greenpoint, Brooklyn, where he was mobbed by admirers. However, some rappers kept his name alive before that. On Company Flow’s critically acclaimed underground rap album, “Funcrusher Plus,” Bigg Jus name-checks Roberts’ graffiti tag while rattling off the names of various graffiti writers in the song “Lune TNS.”

“If you don’t understand this/then obviously it wasn’t made for you,” Bigg Jus says at the end of the track. Roberts’ art was for people who understood, people who got it–no explanation was needed.

His death is a major loss for hip-hop. No explanation needed for that either.
