The recently released “Kurt Cobain: Montage of Heck” by HBO Films is the latest documentary on the late Nirvana frontman. It’s a stirring, fiery look at the troubled genius that for the first time collects Cobain’s journal entries, audio tapes and home videos for a revealing look inside the mind of a man who left us too soon. Filmmaker Brett Morgen got full support from Cobain’s family, and he weaves together the musician’s early years with his rise to stardom, and descent into addiction and mental collapse. If you don’t know anyone with an HBO subscription, now is your chance to see the film when it screens on Sunday, June 7, at Zodiacs, 256 Petaluma Blvd. N., Petaluma. 8:30pm. Free. 707.773.7751.
