Director Katherine Propper's Lost Soulz, a meditative film about music making, self-discovery, and friendship, had its world premiere at this year's Tribeca film festival. Its star, rising rapper Sauve Sidle, saw parallels between his personal journey, his character arc in the film, and the story of Eminem's much-lauded, Oscar-winning turn in Curtis Hanson's 8 Mile. Finding a community of like-minded artists can have a huge impact on a musician and that collaborative spirit runs through 8 Mile and Lost Soulz both behind and in front of the camera. Eminem and Sauve both used their real-world artistic processes to create their on-screen personas, as well as some unforgettable music. We'll also take a look at some of my favorites from this year's Tribeca Film Festival: including the mind-bending, Tierra Whack starring pseudo-documentary Cypher, winner of Best U.S. Narrative Feature.
