Riff Raff floats over a glistening cascade of plucky keys on “Lil Mama I’m Sorry,” pulling a high and hushed sing-song out of his toolbox for the remorseful chorus and rapping the verses in a steady, clear drawl. The video creatively employs a mesh food cover, decorated with embroidered pineapples, as its central prop. Following bleaker “So Throwed,” it’s the second of ten promised Riff Raff videos by self-proclaimed “2013 Cinematographer of the Year” Orbit Didit.
