(AllHipHop News) Vallejo, California rapper E-40 landed three separate brand new albums on Billboards rap chart this week, as his latest releases are sitting in the #5, #6 and #14 positions. The rappers releases Revenue Retrievin Day & Night Shift and the release Heavy On The Grind have sold a total of 30,000 units independently since hitting stores on March 30th. The albums were released on the label Heavy On The Grind, which is run by E-40s son, Droop-E, who serves as President and executive producer of the projects. According to E-40, the success of his independent releases is due to his relentless working on the Internet and other non-traditional avenues to market his products, which each contain different barcodes. I got out there, did my homework and went back to my roots and made these albums for the streets that made me, E-40 told AllHipHop.com. Then I utilized the internet and engaged in social networking by interacting with my fans and I found out what they wanted and what they liked best. Then I considered the state of this economy recognizing that people want the hook up, they want more and thats exactly what I gave them. Most albums have 10 or 12 tracks on them, I exceeded that number then I doubled my product giving my fans who are also consumers a bigger bang for their buck.Each one of the Revenue Retrievin releases contain 19 new songs, while Heavy On The Grind is being sold digitally though iTunes with a whopping 42 tracks from E-40. At FYE stores, the physical CD is packaged with a T-shirt and a 10 free ringtone bundle pack. Additionally E-40 dropped 5 videos that included features from Snoop Dogg, Too Short, Gucci Mane, Mistah F.A.B., San Quinn, Messy Marv, B-Legit, Jazze Pha and others. I would like to thank everyone that participated in making this project happen, the grit dont quit E-40 said.
