Andrew Watt Reveals Unreleased Songs Recorded With Ozzy Osbourne

Unreleased Material and the "Specific Reason"

The musical partnership between Andrew Watt and the legendary Heavy Metal icon Ozzy Osbourne resulted in more material than what was heard on their official collaborations. Watt, who served as the producer for the singer’s final two studio albums, Ordinary Man and Patient Number 9, recently shared that several tracks remain in the archives. However, these recordings carry a significant emotional weight that has made them difficult for the producer to revisit.

During a recent interview with Rolling Stone, Watt revealed that there are "kind of" plans to eventually release this music, though he remained cryptic regarding the inspiration behind the sessions. He emphasized that the songs were not merely leftover tracks but were composed with a particular intent that he is not yet ready to disclose in detail.

"There are some songs that we made for a specific reason. And, yeah, that’s all I can say. They're hard for me to listen to."

A Final Listening Session in Birmingham

The history of these unreleased songs is closely tied to the final days of the singer’s life. Watt recounted a poignant memory from 2025, specifically the night before the Black Sabbath: Back to the Beginning concert held in Birmingham. According to the producer, he was out for a meal with Sharon Osbourne and a small group when he began receiving insistent text messages from the frontman.

"The night before the concert, I actually went in Birmingham with Sharon and a couple of people to go get a curry, and I was texting with Ozzy. He was in his hotel room, and he was, like, ‘Come to the hotel, come to the hotel.’ I was sitting with Sharon and we were both like, ‘He has a big day tomorrow. Maybe I shouldn’t go, ‘cause he’ll get excited and everything.’ But [Ozzy] was, like, ‘No, you’re coming to the hotel. You are coming.’"

Watt eventually complied, bringing a curry to the hotel room where he found the singer engaged in his frequent habit of drawing. The two spent the evening reviewing their unreleased work and documenting their thoughts on the material. This meeting, along with the following day's concert, marked the final time Watt saw the artist. The producer noted that the singer passed away just 17 days after that Birmingham performance, a timeline that has made playing back the recordings a painful experience.

"So I went. I brought a curry with me and sat with him. And he was drawing like he usually does, and we sat and we listened to the stuff that we’d made, and made notes. That and the next day were the last times I got to see him. But we had a beautiful listening session and talked about a lot of stuff."

Mentorship and the Prince of Darkness Legacy

Beyond the unreleased music, Watt reflected on the profound impact the "Prince of Darkness" had on his professional trajectory. Before their collaboration, Watt was primarily established as a pop producer. He credits the singer with not only embracing him within the world of rock music but also providing him with a platform that transformed his career. Watt placed himself in the context of the legendary guitarists the singer had famously selected throughout his solo career, including Randy Rhoads, Jake E. Lee, and Zakk Wylde.

"He had so many things he taught me… And if Ozzy Osbourne chose you, he gave you a career. I always loved rock music, but I was a pop producer before he chose to let me stand next to him… and then I got to do all these amazing things after. But he was the first one. And… he chose Randy Rhoads. He chose Zakk Wylde; Jake E. Lee."

The producer also noted that this spirit of mentorship extended to the very end of the singer's life. He cited the example of Yungblud, whom the frontman personally selected to perform the song "Changes" at the Back to the Beginning concert. Watt observed that the singer had a genuine appreciation for Yungblud as both a person and an artist, and that the opportunity to perform alongside the metal legend was a life-changing moment for the younger musician.

"[He] was on an amazing path before the Back To The Beginning concert, but Ozzy chose ‘Changes’ for him to sing… [He] loved [Yungblud] as a person and what he was doing as an artist and brought him out there. And he sang that song, and it changed his life."

The career of the iconic frontman spanned decades, from his foundational years with Black Sabbath to a solo career that established him as one of the most famous figures in hard rock history. While the "Ozzy & Black Sabbath: Back to the Beginning" film premiere in Los Angeles and various retrospective photo galleries have celebrated his journey from 1969 through 2025, these unreleased songs represent a final, private chapter of his creative output that Watt continues to hold close.
