GB, Gustav Berntsen, is an artist from Copenhagen who crafts texture-heavy, adventurous guitar music cut with a pop sensibility. On August 21, GB shares his new album Herzsprung via AD 93, anticipated with its second single “Starsound”, out today.

“Starsound” stretches out like a long summer’s evening. On the track, GB’s baritone vocal yearnings meet lush, intricate guitar playing and melt into languid textural drumming and collaged saxophone choirs. “Open wide and free”, this is a track simultaneously spacious and detailed. A bonfire on the beach that glows; a space to sit and breathe.

Earlier this spring, GB shared Herzsprung’s first single, “Adrenaline”; sending light from a world of zigzagging guitar, bubbly fretless bass, and rolling percussion.

Herzsprung follows GB’s debut record, the collage-based cult hit Gusse Music, which was released via storied CPH label Posh Isolation in 2024 – the final vinyl LP the label issued before they closed down in 2025.

Herzsprung is GB’s most expansive work yet. Written while living in London, the Copenhagen-based songwriter and producer spent weeks cutting up copies of Metro — one of the city’s free newspapers — to form the lyrical foundation of the songs. In makeshift studios, he began bringing these ideas to life.

Where GB’s debut record was shrouded in a downtempo haze, Herzsprung creates a distinct sound that pushes outward: something more melodic, more full-throated, and more assured. The album draws together a wide spectrum of influences; from the groove-driven fusion jazz of the 1970s to Japanese noise-rock psychedelia, anthemic grunge, and outsider pop. There are traces of the alt-pop qualities that GB shares with his Copenhagen peers, but you hear London’s influence too, an urge to stretch rock tradition and break with form.

After finding himself improbably cast in a viral Jaguar ad in 2024, he used the money to book out a studio villa in the Swedish wilderness, joined by a band of trusted musicians. Over the course of a week, the songs — which had previously existed as memos and notebook scribbles  — took full shape through live performance and collective instinct. Tracked largely live to 24-track tape, the result is a record that feels immediate and playful in its execution. It captures the chemistry of an uncompromising band brimming with ideas and welcoming spontaneity.

Herzsprung sifts through the past and present with urgency, cutting it open so that the future leaks out. On the record’s climax, “Shit River”, GB is backed by a full choir as he screams for “someplace beaming with more colors”. “..and everything in between collapsed, rushing floods of insignificance”.

GB’s new album Herzsprung is out August 21 via AD 93. Find more information and pre-order HERE.
