Consumed by the drawing bug at an early age, Asad Walker would fill reams of paper with superheroes, barbarian swordsmen and crazy letterforms.

At 12 years old, he was relocated from his hometown of Washington, DC to live with relatives in New England. Every holiday, he would travel by train to the old Union Station and visit his family in DC. Through the seventies, he would stay glued to the windows of the train looking at the graffitied walls of the cities he would pass through: Boston, NYC, Philly and Baltimore. He would practice all kinds of lettering in his school notebooks and finally, on his 16th birthday, ran away from home and eventually arrived at the old Greyhound station on New York Ave in downtown DC. The city had a thriving graffiti scene from the 70's through the early 80's. Everywhere were marker tags of individuals, neighborhoods and go go crews. GO GO RANDY, WHATS UP WOODY, A-TEAM, GANGSTER CHRONICLES and many, many more.

Settling on his new identity, "HOBO" started soaking up the newly emerging Hip Hop phenomenon that was growing in DC in 1982. Hanging in the crazy street scene in Georgetown and downtown DC, Asad ran with early crews like Warpath, IBM and HBO and graffiti transplants like SEVEN, E.T. and others. He formed DC's first graffiti crew, KRAZY GRAF BROTHERS with RITZ and SKI in 1983. He became DC's first native graffiti writer to take on New York style tagging and also used the monikers RAGE and JAPAN. In 1986, Asad moved to Brooklyn and with NYC native LADY PARIS to raise their first son. In 1990, Asad returned to DC and its burgeoning graf scene and chose the new title "ULTRA". He worked with Zulu Nation and built his crew KGB back to fighting strength, adding such DC legends as CAST, CRAM, CERT, ROPE, ZYDE, DJ OSO FRESH, HALO, RULE, SEST and COOL "DISCO" DAN. Unfortunately, Asad also made many mistakes and the thuggish street life KGB crew was known for turned on him. In 1997, he was arrested for several assaults and was sentenced to 5 years in Lorton.

Upon his release, Asad ULTRA Walker concentrated on reconciling with and raising his 6 children. He has slowly re-emerged in the graffiti art scene. He was featured in the book "Free Agents: A History of Washington, D.C. Graffiti" and has appeared in two recent documentaries: "Chocolate City Burning" and the upcoming Cool "DISCO" Dan film. He has been busy airbrushing apparel, customizing toys and painting canvases for private collectors, as well as designing websites for diverse clients. KRAZY GRAF BROTHERS have maintained close contact and with new members SIME, WINS, CHE and CAZM keep the vandal spirit alive. 2009 is the 25th anniversary of KGB, DC's oldest and longest-running graffiti crew.
