It’s Sundance weekend again and the star of the show this year is definitely What Happened, Miss Simone? The Netflix-produced Nina Simone documentary traces the life of the famed Jazz singer from her beginnings as a classical pianist, through her rise to fame on the jazz and blues scene. What Happened, Miss Simone does not gloss over Simone’s involvement in the Civil Rights Movement or her struggles with mental illness.

The Park City premiere was made into a real event, followed up with a concert by soul star John Legend in tribute to Simone’s life and work.

"I'm so grateful to be here today honouring the legacy of the wonderful, powerful, dynamic, super-talented Nina Simone," he told the audience at Thursday's event, according to BBC News.

He then performed his own music, as well as three of the late Simone’s best known songs. Legend’s own evocative track for the MLK biopic Selma, which he co-wrote with Common, received an Oscar nomination for Best Soundtrack.
