Marc André Edmonds (1956 – April 18, 1994), also known by the graffiti name ALI and as J. Walter Negro, “The Playin’ Brown Rapper” was an American artist and musician. As ALI, he is best known as the founder of 'Soul Artists' and originator of the cult of Zoo York. As "alter-ego" J. Walter Negro (a cynical take-off on the arch-commercialist J. Walter Thompson advertising agency), he is remembered as the lead singer/songwriter of the proto-hip-hop-rap group 'J. Walter Negro and the Loose Jointz', who had some success with their 1981 release "Shoot the Pump".
