The first trailer for HBO’s documentary “Kurt Cobain: Montage of Heck” has been released. The film offers an intimate look into the first authorized biography of Cobain’s life, with interviews, archival footage, and animation chronicling a young Cobain up until the rise of Nirvana in the 90s. The Brett Morgen directed film premiered at the Sundance Film Festival earlier this year, and will air on HBO on May 4th.
