Who is Xavier Alexander Wahlberg?
Xavier Alexander Wahlberg is an American musician who serves as vocalist and bassist of Upon Stone, a melodic death metal band from the San Fernando Valley signed to Century Media Records.
Born on March 4, 1993, he grew up in the Los Angeles area as the eldest son of Donnie Wahlberg and sound engineer Kimberly Fey. Despite the entertainment industry pedigree that comes with the Wahlberg surname, Xavier has consistently pursued a path in underground heavy metal rather than pop, acting, or any other corner of his family’s world. His band’s debut album Dead Mother Moon, released January 19, 2024, drew praise from publications including Metal Invader, MetalTalk, and Metal Insider for its raw approach to early-90s Scandinavian melodeath influences.
As featured on profiles across the latest xxbrits coverage, Xavier represents a generation of celebrity children who actively resist the path their family name could provide, building credibility in a demanding scene on the strength of their music alone. Upon Stone formed during the pandemic in 2021, released a debut EP within months of coming together, signed to one of heavy metal’s most established labels in 2023, and toured the US with notable acts before their first full-length album arrived. The trajectory is uncommonly fast for an underground metal band with no mainstream promotional apparatus behind it.
Early Life and Background
Childhood and Family
Xavier Wahlberg grew up in the Los Angeles area, raised in a home shaped by the entertainment industry from both sides of his family.
His father, Donnie Wahlberg, became a parent at 23 and was already one of the most recognised names in American pop music as a founding member of New Kids on the Block. His mother, Kimberly Fey, born June 14, 1969, has worked as a sound engineer since her early twenties, giving Xavier early and regular exposure to studio environments, recording sessions, and the technical side of music production. His family’s heritage includes Swedish, French-Canadian, and Scottish roots on the Wahlberg side, a lineage shared with his famous uncle Mark Wahlberg.
His parents married on August 20, 1999, when Xavier was six years old, and separated in 2008 when he was 15. Kimberly Fey was granted custody of both sons following the separation. His father remarried comedian and actress Jenny McCarthy in 2014. Despite the divorce, accounts from multiple biographical sources describe a stable co-parenting arrangement where both parents remained actively involved in Xavier and his brother Elijah’s lives.
Education
Specific details about Xavier Wahlberg’s schools or academic qualifications have not been publicly disclosed.
He is reported to have attended local schools in the United States. His formative development appears to have centred on music rather than academic achievement, with multiple sources noting an early passion for heavy metal that began during his teenage years in the San Fernando Valley. He and future Upon Stone bandmates Wyatt Bentley and Ronny Marks began playing together in various bedroom-project outfits from around age 18, exploring influences including Children of Bodom, In Flames, and Dissection.
Career Journey
Before Fame
Before Upon Stone, Wahlberg spent years playing in informal Valley bedroom projects alongside the musicians who would eventually become his bandmates.
Wahlberg, Bentley, and Marks began their collaborative musical history as teenagers in the San Fernando Valley, grinding through demo-era outfits fuelled by the Gothenburg and Finnish melodeath scenes. These formative years gave the group a shared language and a well-developed sense of the sound they wanted to pursue before Upon Stone became a formal entity. Members also had connections to other regional acts including Vamachara, Xibalba, and Momentum, embedding them in both the Los Angeles hardcore and metal scenes before the new band took shape.
How Xavier Wahlberg Got Started with Upon Stone
Upon Stone formed during the global pandemic in 2021, with Wahlberg, Bentley, Marks, and guitarist Gage Goss using the shutdown period to record their first material together.
The band’s first release, the four-song EP Where Wild Sorrows Grow, came out in late 2021 on the Creator Destructor label. The pandemic formation is significant: rather than a gradual build through open mic nights and regional support slots, Upon Stone arrived with a finished product almost immediately. The EP demonstrated enough focus and intent to attract live bookings, and the band made their live debut in January 2022, opening for Japanese death metal act Kruelty. From that first show, the group pursued touring with unusual aggression for a new band, sharing stages with Unearth, Gatecreeper, and 200 Stab Wounds before they had a label deal.
Breakthrough Moment
Upon Stone signed with Century Media Records in July 2023, one of the most significant heavy metal labels globally, a deal that confirmed the band’s standing in the melodeath underground well before their debut album dropped.
The signing announcement cited the band’s visceral energy and their commitment to early-90s melodeath influences including At The Gates, In Flames, and Dissection. The label deal came with the release of the single “Onyx Through the Heart,” which circulated widely across metal media platforms. The debut album Dead Mother Moon, a nine-track record produced and mixed by Taylor Young at The Pit, followed in January 2024. The album featured guest vocals from Brian Fair of Shadows Fall on “Paradise Failed” and a cover of the Misfits track “Dig Up Her Bones” as a bonus track, with cover artwork by Andreas Marschall, the German artist responsible for artwork for Dimmu Borgir and In Flames. MetalTalk described the album as phenomenal and called it a potential gateway record for a new generation of melodeath listeners.
Career Today
As of 2026, Xavier Wahlberg continues working with Upon Stone in Los Angeles, focused on live performance, rehearsals, and creative development following the debut album cycle.
The band toured extensively in support of Dead Mother Moon, playing dates with Xibalba, Warbringer, Earth Crisis, Devil Master, Fuming Mouth, and Final Gasp. Upon Stone’s positioning between the Los Angeles hardcore and metal audiences gives them an unusually broad live draw for a melodeath band. Wahlberg maintains no personal social media presence, with all band activity running through Upon Stone’s official channels on Instagram, Bandcamp, and Spotify. The next phase of the band’s recorded output had not been publicly announced as of early 2026.
Music Style and Niche
Upon Stone operates in melodic death metal, specifically drawing from the early-90s Gothenburg and Finnish scenes, with Xavier Wahlberg’s vocals described as raw-throated and intense throughout the band’s recorded output.
The band’s declared influences include At The Gates (Slaughter of the Soul), In Flames (The Jester Race), Dissection (Storm of the Light’s Bane), Children of Bodom, and Dismember, all foundational texts of the Scandinavian melodeath tradition. The Century Media press material positioned their sound as a rebirth rather than a revival of that era: not nostalgic recreation but a band genuinely raised on those records treating them as a living grammar. Metal Insider noted a strong metalcore element running through Dead Mother Moon alongside the melodeath core, reflecting Upon Stone’s roots in the LA hardcore scene as much as the European metal tradition.
Wahlberg handles both vocals and bass for the band, a dual role that defines the rhythm section’s character alongside drummer Wyatt Bentley. Guitarists Ronny Lee Marks and Gage Goss build the harmonic architecture that melodeath demands. The band’s live reputation has built quickly on the strength of their intensity as a unit, with touring credentials that span hardcore-adjacent bills as well as pure metal lineups, demonstrating the cross-audience appeal that distinguishes Upon Stone in their scene. For readers following the broader landscape of British and American entertainment stories, Upon Stone represents a notably underground success story from within one of America’s most publicly scrutinised families.
