In 2010 he surpassed a new benchmark when he signed to Heavy On The Grind owned by his first son also Artist/Producer Droop-E. Together they released E-40s 13th and 14th albums entitled Revenue Retrievin Day Shift and Revenue Retrievin Night Shift. That very effort spun the Bay Area s famed Ambassador as one of the hottest commodities in Hip-Hop with the smash hit record Bitch featuring Too Short and 50 Cent. On March 29, 2011 E-40 once again came back with yet another two new classic albums entitled "Revenue Retrievin Overtime Shift" and "Revenue Retrievin Graveyard Shift" to mark the 15th and 16th albums from the Bay Ambassador. Now E-40 is set to change the game again with the release of 2 simultaneous new studio albums on the same day titled, Sharp On All 4 Corners: Corner 1 and Corner 2. With both releases, expect E-40 to deliver tracks sharper than a two edge sword!
