Chris Willman Senior Music Writer and Chief Music Critic More than ever, rock stars were TV stars in 2023 — in the form of subjects for television documentaries — and so were their brethren in pop, hip-hop, K-pop and Latin music. Some of these TV films or docuseries were vanity projects used to promote new albums, of course; others started off as “making of” projects and ended up catching a star in a moment of real psychological crisis. It wasn’t all cinema verité; historical overviews capturing the full breadth of an artist’s career or even a genre still had their place in the pop-doc landscape. Four films or limited series stand out in the subgenre of docs that were initially commissioned to capture an album or tour and, through circumstances, evolved into something deeper or darker. “Selena Gomez: My Mind & Me” (Apple TV+) was going to be a tour documentary, but then, when an emotional breakdown caused her to pull off the road, it became a portrait of a singer coming to terms with mental illness.
