Artemas Diamandis went from watching a Kurt Cobain documentary at 16 to landing a billion-stream single at 24 — and the tour routing that follows that kind of arc tends to be revealing. The Stubb’s outdoor date on September 19 isn’t a hedge. It’s a statement that the audience for his particular brand of synth-heavy, bass-driven alt-pop — the kind of music that gets described as after-hours and means it — is real and physical, not just a stream count.
About Artemas
The Oxfordshire-born, London-based singer, songwriter, and producer built his sound around instinct rather than formula. He describes his process as sitting down at a keyboard or guitar and trying to “speak a song into existence” — which, for “I Like the Way You Kiss Me,” resulted in a single that hit No. 1 in eight countries, reached No. 3 in the UK, No. 12 on the US Hot 100, and crossed a billion Spotify streams. The BRIT Award nomination followed.
He’s been releasing material steadily since 2020, but the arc accelerated fast: “If U Think I’m Pretty” went viral on TikTok in late 2023, the debut mixtape Pretty dropped in February 2024, and LOVERCORE — 14 tracks of dark, seductive synth-pop — came in 2025. March 2026 brought getting up to no good, a 10-track project the press tagged as “a perfectly-curated playlist for making bad decisions on a night out.” The lead singles “psychokiller” and “myself” set the tone: minor-key, bass-forward, with a sense of emotional damage handled as style.
The Room
Stubb’s Waller Creek Amphitheater holds 2,500 — one of Austin’s most reliable mid-size outdoor stages, and now firmly in Live Nation’s portfolio, which shapes the routing decisions that land there. The Artemas show is GA floor. Doors open at 7:00 PM. September in Austin can still run warm at showtime, so plan accordingly.
Support & Tickets
Henry Morris opens. The 23-year-old LA-based singer-songwriter — formerly half of a duo called Playyard — makes reverb-drenched, orchestral-tinged indie-alt that pulls from Lana Del Rey and Arctic Monkeys in roughly equal measure. His self-titled album dropped in May 2026. Worth arriving early.
