The Weeknd's 2011 mixtape, Thursday, is the second installment of his Trilogy project, featuring R&B with down-tempo, dream pop, and hip hop influences, exploring themes of libertinism, drug use, and toxic relationships through the eyes of his persona. The mixtape features production by Doc McKinney and Illangelo, guest vocals from Drake on "The Zone," and a generally darker, edgier, and more confrontational sound compared to his debut, House of Balloons.
