In the first official clip from "Amy," the upcoming documentary about Amy Winehouse, the late singer's manager discusses the evolution of her songwriting process.

"We'd recorded quite a few demo recordings, and I started to talk about whether she ever considered writing," says Nick Shymansky in the nearly minute-long clip. "She said she's not sure about writing songs, but she's written a lot of poems. She knew full well she'd been writing songs, but they were very personal songs."

The teaser features footage of Amy joking, laughing, and smoking a cigarette, and offers a glimpse at some of her handwritten lyrics. Amy can also be heard singing in the background while Shymansky speaks.

Winehouse died in 2011 at the age of 27, amidst a notoriously public struggle with drugs and alcohol. Last month, the singer's family blasted "Amy" for being "misleading," and expressed their wish to "disassociate" from the Asif Kapadia- directed film.

"Amy" is set to be released July 3 in the U.K. and will be screened this month at the Cannes Film Festival.
