Who Is Xavier Alexander Wahlberg?
Xavier Alexander Wahlberg is the first child of Donnie Wahlberg and Kimberly Fey.
His father became internationally famous as a member of New Kids on the Block before developing a successful acting career.
However, Xavier did not follow his father’s musical style.
Instead, he became involved in heavy metal, particularly the aggressive and melodic sound associated with Scandinavian death metal.
His professional work includes performing as a vocalist and bassist with Upon Stone.
The band developed a following through recordings, concerts, and appearances alongside established heavy metal groups.
Xavier therefore has an independently documented music career rather than simply being known as a celebrity’s son.
Xavier Alexander Wahlberg’s Early Life and Childhood
Xavier was born on March 4, 1993.
His parents had been in a relationship before his birth and married several years later.
At the time, Donnie Wahlberg was already famous through New Kids on the Block.
The group’s popularity during the late 1980s and early 1990s made Donnie a recognizable figure among pop music audiences.
Growing Up With a Famous Father
Xavier spent his childhood in a family connected to the recording industry and television.
His father continued developing professional opportunities while balancing the responsibilities of parenthood.
Donnie later explained that becoming a father at 23 dramatically changed his priorities.
In a 2013 interview, he said that fatherhood encouraged him to concentrate more on providing for his family than on building his personal legacy.
Although Xavier occasionally appeared in family photographs, his parents generally avoided making his private life a regular subject of entertainment reporting.

The recording established the group’s early sound and attracted interest within underground metal communities.

The band drew inspiration from influential Swedish melodic death metal groups.
Its sound combined powerful guitars, fast drumming, and harsh vocals.

The label is known for working with established heavy metal artists.
The announcement identified Xavier as the band’s bassist and vocalist.
Other members included Wyatt Bentley, Ronny Lee Marks, and Gage Goss.
The band also released the single Onyx Through the Heart.
This agreement represented an important professional achievement and expanded its opportunities for recording and touring.
Dead Mother Moon: Xavier’s First Major Album

The recording featured melodic death metal influenced by the genre’s earlier European traditions.
Its tracks combined aggressive instrumental arrangements with atmospheric themes.

It featured original songs and a cover of a Misfits track.
German artist Andreas Marschall created the album artwork.
The band also released promotional music videos supporting the record.
Xavier contributed vocals and bass to the band’s early established lineup.
The release introduced Upon Stone to a wider international audience of metal listeners.
End Time Lightning: New Music in 2025

Touring With Other Metal Bands
Following the release, Upon Stone joined a North American tour supporting Creeping Death and Kruelty.
The tour included performances in Colorado, Canada, Washington, California, and other locations.
The band’s continued activity demonstrated that Xavier’s music career extended beyond a single album.
By 2025, some lineup databases identified Xavier primarily as a vocalist rather than continuing to list him on bass.
However, his best-established earlier credits include both vocals and bass.
