A documentary on Leon Russell is finally being released, 43 years after it started filming.

A Poem Is a Naked Person was born during Russell’s demo recording sessions for his 1973 album, Hank Wilson’s Back.

After filmmaker Les Blank spent more than two years on the project – first in Oklahoma for then for the album’s recording in Nashville –  tensions arose between Blank and Russell.  But ultimately, it was creative differences between the two that meant the film never saw the light of day, reveals Russell in a new Rolling Stone interview.

After Blank’s death in 2013, the filmmaker’s son took on the project. Russell let go of some of his reservations about the film, and it finally premiered this past year at the SXSW Film Festival.

A Poem is a Naked Person officially opened at New York City’s Film  Forum on Wednesday, with Russell in attendance.
