LOS ANGELES — Duncan Sheik, who earned a Grammy nomination for his ubiquitous 1990s hit “Barely Breathing” and won a Tony Award for composing the music for “Spring Awakening,” died Thursday. He was 56.

“It is with profound sadness that we confirm the passing of Duncan Sheik,” a statement posted Friday on Sheik’s Instagram account read. “The world has a lost a singular talent, and deeply influential voice in music and theater.... Duncan’s artistry touched many and leaves an indelible mark on the cultural landscape.

“Duncan was a father, husband, son, brother, and friend. He will be remembered for his sensitivity, wit, inteligence, and depth of spirit he brought to those who knew and loved him.”

The statement added that “Duncan passed away last night surrounded by love.”

His mother, Suzanne Sheik, told the New York Times that her son died of organ failure. A statement posted to his Instagram account Thursday said that Sheik was “receiving medical care and remains in critical but stable condition.”

Sheik, a New Jersey native, went to Brown University, where he played in an early band with singer-songwriter Lisa Loeb. His 1996 self-titled debut LP was a hit on the strength of “Barely Breathing,” an exemplar of the upbeat coffee-shop rock that emerged in the wake of grunge on the pop charts. The single stayed on the Hot 100 for over a year, and the album went gold, earning earned him a Grammy nomination for male pop vocal performance.

Sheik’s follow-up, 1998’s “Humming,” featured rich orchestration, but he already had an eye on Broadway (his sister Kacie Sheik is a stage actor who has appeared in “Hair,” “American Idiot” and “Because of Winn-Dixie,” for which Duncan wrote the score).

He wrote his 2001 album “Phantom Moon” with poet and playwright Steven Sater, whom he’d again collaborate with on the score for the musical “Spring Awakening” — based on the play by German Expressionist Frank Wedekind, which won him a Tony Award — and “Alice by Heart.” His 2009 album “Whisper House” yielded a companion musical of the same name. He also composed the score for the 2004 film “A Home at the End of the World.”

While Sheik sought treatment for alcohol addiction after canceling a tour in 2011, his stage and studio career never slowed. Other major stage credits include hit productions of “American Psycho,” “Bob & Carol & Ted & Alice,” the thriller “Noir” and “The Secret Life of Bees,” along with Shakespeare’s “Twelfth Night” and “The Taming of the Shrew.” His last album, “Claptrap,” came out in 2022.
