BOOK OF WYRMS

US heavy metal psych voyagers BOOK OF WYRMS return with “Proficient Dreamer”, the second single from their highly anticipated new album, Megacelestial, out December 11, 2026, via Argonauta Records on CD, colored vinyl, and digital formats. Alongside the new track, the band reveal the complete details of their upcoming fourth full-length, marking a bold new chapter in their ever-evolving sonic journey.

Following the release of “Slime Fever”, which offered the first glimpse into the new record, “Proficient Dreamer” provides another taste of the band’s renewed creative direction. Faster, dirtier, and more direct, Megacelestial captures Book of Wyrms embracing a sharper, more aggressive heavy metal attack without abandoning the psychedelic spirit and otherworldly atmosphere that have always defined their sound.

Formed in 2014 through a shared love of Hawkwind and ZZ Top, Book of Wyrms have spent over a decade exploring the outer reaches of heavy music. Their latest album reflects a significant shift in both energy and approach, inspired by the arrival of drummer Brian Wiltz, whose powerful, straightforward playing has helped reshape the band’s songwriting and dynamics.

For Megacelestial, the band also collaborated with Rob Wrong (Wrong Way Recording, Witch Mountain), who handled the mix for the first time in the band’s history. Drawing inspiration from the melodic power of 80s Judas Priest, Dio, Thin Lizzy, Scorpions, Queen, and Motörhead, the new material delivers a more immediate and hard-hitting sound, balancing razor-sharp guitar work, fuzz-driven low end, atmospheric synthesizers, and commanding female vocals.

The band previously described their new approach as making music for “driving across the country on no sleep”, a fitting description for an album built around momentum, intensity, and a refusal to settle for anything less than full impact.

With Megacelestial, Book of Wyrms push their cosmic heavy psych into more forceful territory, delivering a record that promises to resonate with fans of Judas Priest, Blood Ceremony, Earthless, The Black Angels, Castle Rat, and Howling Giant.

“Proficient Dreamer” is available now on all digital platforms.

US heavy metal psych outfit Book of Wyrms return today with their new single “Slime Fever”, offering the first glimpse into their forthcoming new album, with further details to be revealed soon.

Formed in 2014 out of a shared devotion to Hawkwind and ZZ Top, Book of Wyrms describe themselves as a four piece heavy metal psych band with extensive experience jamming in outer space, steadily building a reputation in the US underground through their blend of heavy riffs, psychedelic textures and driving energy.

“Slime Fever” captures a clear shift in momentum for the band. The addition of drummer Brian Wiltz has injected a new level of intensity and directness into the songwriting, with a more aggressive and straightforward approach that still leaves space for dynamics, restraint and unexpected turns. Wiltz’s background outside of traditional heavy music also brings a broader rhythmic perspective, knowing when to support the song and when to push it into more explosive territory.

For the first time, the band also worked with a dedicated mixer. Rob Wrong (Wrong Way Recording, Witch Mountain) handled the mix, opening up a new sonic dimension for Book of Wyrms and helping shape a sound that feels both sharper and more expansive than ever before. His approach aligned naturally with the band’s vision, drawing on reference points such as Dio’s Last in Line and Judas Priest’s Turbo, while still allowing space for unexpected creative directions in the mix.

Stylistically, the band continues to evolve while staying rooted in their core influences. Alongside their enduring love for Rainbow, Hawkwind and Monster Magnet, Book of Wyrms found themselves drawing inspiration from 80s Judas Priest, Thin Lizzy, Scorpions, Queen and Motörhead, aiming to create music built for movement and intensity. The result is a collection of songs shaped with a strict approach to composition, where anything that did not “hit” with full impact was left behind.

“Slime Fever” stands as the first transmission from this new era: faster, dirtier and more focused, setting the tone for what is to come from the forthcoming album.
