Aaron Lazar did the impossible.

After being diagnosed with ALS in January 2022, the Broadway veteran rallied together nearly 80 of of the biggest and brightest stars across the music, film, television and theater industries for a powerhouse cover of "The Impossible Dream."

PEOPLE has a first look at the music video for the single, which was recorded on June 13 in New York City. It's the cornerstone song off Lazar's first album, Impossible Dream, out Thursday, Aug. 23.

Among the stars featured on the tune are Josh Groban, Kristin Chenoweth, Neil Patrick Harris, Lin-Manuel Miranda, Leslie Odom Jr., Kelli O'Hara, Brian Stokes Mitchell, Adrienne Warren, Shoshana Bean, Kate Baldwin, Norm Lewis, Loren Allred, Liz Callaway, Joanna Gleason, Brian d'Arcy James, Tony Yazbeck, Christy Altomare, Adam Jacobs, Max Von Essen, Betsy Wolfe, Christiane Noll and Marc Kudisch.

There's also a special appearance by legendary rock singer Sting, who composed the score for The Last Ship — the 2014 Broadway musical that starred Lazar.

Backing the soloists up are a choir of close friends, family and famous faces.

Credited names include Michael Berresse, Jeff Bowen, Corey Cott, Anthony Fedorov, Travis Leland, Michael Minarik and Jessica Phillips, among many more.

"It's incredible, isn't it?" Lazar told PEOPLE at the recording. "How many times in life do you get to be in the room with so many people you care about? I feel so lucky to call these people friends, and honored that they all generously agreed to lend their voices to this project designed to give hope to so many others. It's just a gift."

"The Impossible Dream," first introduced in the 1965 musical The Man of La Mancha, has special meaning for Lazar. Determined to heal from ALS, the father of two has adopted the beloved song as his personal mantra.

"I've learned a lot over the last couple of years through some unimaginable adversity, and one of the things I've learned is how much love there is in my life that is just beyond," Lazar explained at the recording. "We are doing something that not just helps me heal, but as I've started to share my story, we are helping raise awareness to end this terrible disease and help other people live their impossible dreams."

In addition to the epic recording of "The Impossible Dream," Lazar's album will also include collaborations with many of the aforementioned soloists. The 9-track LP will feature the National Children's Chorus and the Broadway Inspirational Voices, as well as a special duet with the late Rebecca Luker — who died at the age of 59 in 2020, just 10 months after receiving her ALS diagnosis.

A portion of the album's proceeds will benefit the ALS Network, an organization that not only helps those with ALS get access to quality care and support, but also drives the discovery of prevention strategies, treatments and cures for the degenerative neurological disease.

Lazar first announced his album back on June 14, a day after the group recording session.

"This album is a testament to the power of love and community," he said in a release. "I'm incredibly grateful to collaborate with such extraordinary artists and friends, and honored to share my story, raising awareness to end ALS."

Recording an album was initially not in Lazar's plan, but came together shortly after PEOPLE helped share his story in early February.

My buddy Jonathan Estabrooks over at Emitha Studios called me up after seeing my story and was like, 'Hey, do you want to make an album?' " Lazar told PEOPLE later that month, during a sit-down in Los Angeles. "And I've never done an album of my own, but I just had this idea to make something with inspirational songs that are full of love, hope and healing. And we started dreaming up what this could be."

Getting stars to join wasn't hard for Lazar. "I just started making calls and within two weeks, Sting, Leslie Odom, Jr., Kelli O'Hara — all these incredible people had come on board," Lazar said. "Everybody just said yes."

That sort of love is par for the course from the Broadway community, a fact that was reinforced to Lazar when he went public with his ALS diagnosis.

"The second I said it I was just inundated with the kindest, most supportive messages," Lazar recalled. "And I'm lucky that I had waited two years between when I got my diagnosis and when I told people, because with all the love that poured it, I would not have known, years ago, how to even process that. It would have been overwhelming."

"But again, I'm so thankful to everybody for all that they've done to support me," Lazar stressed. "They've made my impossible dream a reality."

Impossible Dream is available now. Support can be made by purchasing, streaming and/or sharing the album.
