In her new documentary, "Janis: Little Girl Blue," Oscar nominated director Amy Berg explores the life of Janis Joplin who died 45 years ago last month.

Berg had anything but an easy time making the documentary. She went into detail in a recent interview with Alex Cohen, "There were so many complications with her estate and the rights. And there were years where I could not listen to Janis Joplin because we had been going and then everything fell apart for about two years. And so I think that there's this endurance test that she put me through or something."

But Berg said that it was worth it, "She set a different path for feminists to take. She broke through doors that were untenable for women at the time. And she said things and did things that were so outrageous back then... I think that we're so fortunate to have Janis at the first lady of rock and roll."
