Shock G, who was born Gregory Edward Jacobs and died at age 57 on April 22 of this year, wore many hats besides the one on his head: He was a founding and consistent member of the popular hip-hop group Digital Underground, a songwriter, a visual artist, a performer, a pianist, a music producer and a mentor to other hip-hop artists. On Saturday, people gathered in downtown Oakland at The Bay Area Honors Shock G, a part of the month-long Black Arts Movement Business District Fest, to honor this unique rapper, whose career spanned more than 30 years, many of which were spent in the Town.
