In one of his first dealings as an advisor to the Prince estate, Spotify executive Troy Carter is helping negotiate a deal that could give one major streaming service exclusive rights to one of the late pop star’s unreleased concert films as well as rights to make a documentary about the film, sources tell Billboard.

The potential multimillion-dollar deal, which hasn’t yet been completed, could be the latest prize in the competition among streaming companies, a battle that has been ratcheting up lately as top players shell out millions for exclusive content that can help them stand out from the pack.

On the table is a film of Prince’s Aug. 3, 1983 performance in Minneapolis where he debuted several of the songs released on the soundtrack to his 1984 movie Purple Rain, plus additional footage that a buyer could use to produce a documentary about the making of the film, sources say. The storied show at Minneapolis’s First Avenue nightclub was a surprise gig billed as a benefit for the Minnesota Dance Theatre, with a set list that included “Let’s Go Crazy” and “Purple Rain.”
