The documentary series is based on the book of the same name by true-crime author Michelle McNamara, which details her investigation into the Golden State Killer. McNamara, who was also Patton Oswalt’s wife and a friend of Mann’s, died in 2016 of an accidental overdose on prescription meds. The Golden State Killer was eventually caught in 2018, thanks in part to her work.
“My husband, Michael Penn, and I had been close friends with Patton and Michelle for many years and were very familiar with the ups and downs of her research,” Mann said in a statement. “We were completely devastated by her death. I was incredibly moved by Patton’s dedication to getting her book finished and was so happy when he reached out about recording a version of ‘Avalanche’ for the show. Michael produced and recorded it at home, and we were both honored to hear it at the start of every episode.”
Aimee Mann released her most recent studio album, Mental Illness, in 2017.
