The Bay Area's ambassador E-40 is one of those rare veterans in hip-hop that gets better with time. After his excellent appearance on Big Sean’s “IDFWU,” 40 Water is getting back to his independent grind, keeping in tradition of releasing multiple volumes of his album for fans. This year, we’re getting The D-Boy Diary 1 & 2, and the first single is “Slappin” featuring Vallejo’s Nef the Pharaoh and Virginia’s D.R.A.M. Produced by Rick Rock Beats, the bouncy cut has 40 talking his shit: “Look at my IG, I’m everywhere!” Listen to it below.
