For millions of passionate gamers and lovers of contemporary video game orchestration, the wait is finally over. Supergiant Games, in partnership with the Game Music Festival (GMF), has officially released the complete concert film Ballads of the Underworld for free streaming on YouTube. Captured in breathtaking 4K resolution, the performance immortalizes a monumental night in video game music history: the June 27, 2026, one-night-only showcase at London’s prestigious Royal Festival Hall.
The concert, which marks a major milestone celebrating the sixth anniversary of the critically acclaimed original Hades, bridges the musical landscapes of both Hades and its wildly successful sequel, Hades II. Fans are treated to soaring orchestral arrangements of the soulful laments, haunting hymns, and unforgettable siren songs that have anchored the journeys of both Zagreus and the Princess of the Underworld, Melinoë.
Headlining the performance are Supergiant Games’ visionary composer Darren Korb and signature vocalist Ashley Barrett, whose creative partnership has defined the sonic identity of the studio for over a decade. They are joined by an elite lineup of special guest voice actors breathing physical and vocal life into their digital characters: Judy Alice Lee, the voice of Melinoë; Erin Yvette, the mesmerizing voice of Scylla; and Colin Ryan, the voice of Apollo. Providing the majestic sonic backdrop is the world-renowned London Mozart Players, led by Grammy-nominated and BAFTA-winning conductor Austin Wintory.
By making this high-definition audiovisual recording publicly available, Supergiant Games and GMF ensure that a performance originally locked behind the doors of a single London venue can now be experienced by a global audience, cementing video game soundtracks as legitimate, high-art cultural phenomena.

Supporting Data & Production Background
The production scale of Ballads of the Underworld reflects the massive commercial and critical footprint of the Hades franchise. Bringing indie game music into a centuries-old, prestigious classical venue like London’s Royal Festival Hall required an unprecedented alignment of logistical coordination, arrangement mastery, and audio engineering.
The Ensemble and Leadership
- Darren Korb: Composer, audio director, and original co-vocalist for Supergiant Games, whose genre-blending style serves as the creative engine of the franchise.
- Ashley Barrett: The ethereal vocalist whose haunting refrains have defined tracks like "In the Blood" and "Good Riddance."
- Austin Wintory: Conductor for the evening. A Grammy nominee and BAFTA winner renowned for his work on Journey, Wintory masterfully bridges the gap between interactive game audio and traditional symphonic composition.
- The London Mozart Players: Britain’s oldest chamber orchestra, bringing precision, dynamic range, and classical pedigree to modern indie-game compositions.
- Character Vocalists: Judy Alice Lee (Melinoë), Erin Yvette (Scylla of Scylla and the Sirens), and Colin Ryan (Apollo) stepping out of the recording booth and onto the concert stage to perform their characters’ in-game musical numbers live.

Official Responses
Leaders from both Supergiant Games and the Game Music Festival shared their insights on the significance of the project, highlighting the cultural crossover between gaming and classical orchestral performance.
Supergiant Games shared their enthusiasm with the community:
"If you’ve enjoyed the music of Hades and Hades II, you do not want to miss this once-in-a-lifetime performance featuring live orchestral arrangements of all your favorite songs from both games, and more! This is a 4K recording of the one-time-only concert that took place at The Game Music Festival in London’s Royal Festival Hall on June 27, 2026. It features Supergiant’s composer Darren Korb and vocalist Ashley Barrett, with special guests Judy Alice Lee, Erin Yvette, and Colin Ryan, all with orchestral accompaniment by the London Mozart Players conducted by Austin Wintory. Our thanks to Game Music Festival for making everything possible!"
Mateusz Pawlak, Founder of Game Music Festival, emphasized the long-term vision behind capturing and distributing these live experiences:
"The music of Hades has such a strong identity and such a devoted audience. We’re so happy to be able to give this performance a life beyond the concert hall and make it available to everyone. It was an incredible privilege to work with such a brilliant group of vocalists, musicians, and creatives and to capture the performance for audiences around the world."
Pawlak further elaborated on the philosophy driving GMF’s 2026 slate—which includes both the Diablo 30th Anniversary concert and Ballads of the Underworld:
"A concert is only one way of connecting people with game music. The most exciting projects happen when the music becomes the starting point for something bigger—a live performance, a film, a record, a conversation, or a completely new kind of audience experience. Our job is to find the right format for the music and the people who made it."
Implications
The release of the Ballads of the Underworld 4K concert film carries profound implications for the video game industry, the classical music establishment, and the future of interactive entertainment audio.
- Legitimization of Game Music as High Art: By hosting these performances in elite cultural epicenters like the Royal Festival Hall and pairing indie developers with institutional ensembles like the London Mozart Players, organizations like GMF are breaking down archaic barriers between "pop culture" and "high culture." Video game scores are increasingly recognized as complex, emotionally resonant symphonic works that can stand entirely on their own merit outside of interactive gameplay.
- Archival and Global Accessibility: In the past, video game orchestral events were transient, ephemeral moments experienced only by those fortunate enough to live near major metropolitan venues on specific nights. By investing in high-end, 4K multi-camera audiovisual recordings distributed freely on platforms like YouTube, creators ensure that global fandoms—regardless of geography or economic access—can participate in these cultural celebrations.
- Transmedia Storytelling and Character Immersion: Having voice actors like Judy Alice Lee, Erin Yvette, and Colin Ryan perform musical numbers live alongside the composer creates an unprecedented parasocial bond between players and their favorite fictional worlds. It transforms characters from static digital assets into living, breathing artistic personas.
- A Blueprint for Future Collaborations: Following the dual success of The Infernal Symphony (Diablo) and Ballads of the Underworld (Hades), GMF has established a repeatable, highly professional blueprint for game publishers. Moving forward, major interactive entertainment franchises will likely view live concert filming and companion soundtrack releases not as mere marketing afterthoughts, but as essential pillars of franchise longevity and cultural legacy.
As Ballads of the Underworld streams to screens across the globe, it proves once and for all that whether navigating the fiery pits of Tartarus or the shadowy paths of the Crossroads, the music of Supergiant Games will continue to echo far beyond the confines of the monitor.
