We first caught wind of Zed Bias's grime supergroup Sleepin' Giantz back in 2010, when the dubstep and garage innovator included "Badungdeng" in his XLR8R podcast. Since then, Zed Bias (a.k.a. Maddslinky a.k.a. Dave Jones) and his collaborators—Rodney P of the influential British rap group London Posse and grime/hip-hop emcee Fallacy—have composed a self-titled LP, which is out now. "Hand Grenade" is our first look into the album since "Badungdeng," and boasts Rodney P's and Fallacy's energetic rap styles as they trade off vocal duties over the surging, low-frequency grittiness of Jones' garage-leaning instrumental.
