Wolfgang formed Mammoth WVH initially as a solo project while he was still a part of Van Halen, but became his full-time band after their disbandment in 2020 as a result of Eddie's death.

[5] In June 2019, Wolfgang appeared as a guest on his mother Valerie Bertinelli's Food Network television show, and announced that he had finished recording the album.

[6] The first single "Distance" was released on November 16, 2020, as a tribute to his father, who died from a stroke on October 6, 2020, after years of battling throat cancer.

[7] Wolfgang later revealed that he began work on the song years prior as a coping strategy, while his father's health was declining, stating that he knew there would be an eventual death of his beloved parent, bandmate, and best friend.

When asked why he recorded the entire album himself, he stated that he wanted to challenge himself and referred inspiration from Dave Grohl's work as the sole member of the early years of Foo Fighters.

The younger Van Halen admired that Eddie had a multi-faceted role including serving as the original lead singer of Mammoth, and with his intentions to solely write, perform, and produce the album, he settled on the name.

"[12] Sonic Perspectives declared that while the musician was initially met with doubt and criticism, the album "would make [his father] proud" and to "expect to hear his name in this business for many years to come.

"[13] While Riff Magazine criticized the calculated technique and perceived lack of risk-taking, they praised his musical technicality and acknowledged that "he can go in just about any direction he wants, not only because of his last name, but because he really is that good.

"[14] Consequence Heavy stated that while the diversity of songs creates a lack of cohesion, it is a "deeply personal and musically rewarding debut" while declaring the musicianship to be "virtuosic".
