Duncan Sheik Dead at 56: ‘Barely Breathing’ Singer’s Cause of Death

• Duncan Sheik, the singer behind 1996’s “Barely Breathing” and the Tony-winning composer of Spring Awakening, died Thursday, Sept. 17, at a Manhattan hospital. He was 56.
• His mother, Suzanne Sheik, said the cause was heart failure that led to cardiac arrest. He had been hospitalized since early September.
• Lea Michele, who starred in Spring Awakening, said his death “does not seem real.” He had two new stage projects opening this fall.

Duncan Sheik, whose “Barely Breathing” was one of the defining radio songs of the late ’90s, died on Thursday, Sept. 17, in New York City. He was 56.

His mother, Suzanne Sheik, told The New York Times that he died of heart failure that led to cardiac arrest. A day earlier, his family had said he was in “critical but stable condition.”

“It is with profound sadness that we confirm the passing of Duncan Sheik,” his family said in a statement. “The world has lost a singular talent, and deeply influential voice in music and theater.” He “passed away last night surrounded by love,” the statement added.

What was Duncan Sheik’s cause of death?

Heart failure leading to cardiac arrest, according to his mother. The family has not said what put him in the hospital or what caused the heart failure.

The two terms aren’t the same thing. Heart failure is a gradual condition: the heart keeps beating but can’t pump enough blood for what the body needs, according to the American Heart Association.

Cardiac arrest is sudden. The heart’s electrical system misfires, the heart stops pumping, and blood stops reaching the brain and other organs. Without CPR or a defibrillator within minutes, it is fatal.

Neither is a heart attack, which the AHA defines as a blocked artery cutting off blood to part of the heart. A heart attack can trigger cardiac arrest, but his family has not said one happened.

How long was Duncan Sheik in the hospital?

At least two weeks, and he posted about it himself. In early September, Sheik shared hospital selfies on Instagram, joking with fans and asking, “Do you like (good) magazines?”

On Sept. 6, he wrote that he was “still bored in hospital” and expected to be released “in 60 hours.” That release never came.

On Wednesday, Sept. 16, his family posted that he was “in critical but stable condition” and receiving medical care. He died the next day.

Who was Duncan Sheik to Lea Michele?

He wrote the songs that made her a star. Lea Michele originated the role of Wendla in Spring Awakening, the rock musical Sheik wrote with lyricist Steven Sater, opposite Jonathan Groff as Melchior.

She met Sheik at 14, years before the show reached Broadway in 2006. On Instagram, Michele said she used to listen to a tape of him singing the demos outside her middle school before her first audition.

I am at a loss for words. This one hurts and does not seem real.

— Lea Michele, on Instagram

She thanked him “for everything you gave us. And for the time we had together,” and posted rehearsal footage of Sheik on acoustic guitar as she sang “Mama Who Bore Me,” with Groff looking on.

Sater, his collaborator of more than two decades, posted a photo of the two with a lyric from one of their songs.

What was Duncan Sheik known for?

Two careers, back to back. “Barely Breathing,” from his 1996 self-titled debut on Atlantic Records, spent 55 weeks on the Billboard Hot 100 and earned him a Grammy nomination for best male pop vocal performance.

He released nine studio albums, the last of them Claptrap in 2022. By the 2000s, though, most of his energy had gone to the theater.

Spring Awakening, adapted from Frank Wedekind’s 1891 play about teenagers in 19th-century Germany, opened on Broadway in December 2006. In 2007, it won eight Tony Awards, including best musical.

Sheik took home two of them himself, for best original score, shared with Sater, and for best orchestrations. The cast album won the Grammy for best musical show album in 2008.

He followed it with scores for American Psycho, which reached Broadway in 2016, Alice by Heart and The Secret Life of Bees.

Sheik is survived by his partner, Nora Ariffin, and their daughter, Ines, 7.

What was Duncan Sheik working on?

Two shows he won’t see open. Memoirs of Amorous Gentlemen, his musical based on Moyoco Anno’s manga, starts off-Broadway performances Sept. 25.

And a new Spring Awakening revival, directed by Danya Taymor, begins a 12-week run at Studio Seaview on Nov. 27, with opening night set for Dec. 17.
