Thee Soreheads
Bold, female-fronted punk band Thee Soreheads blend raw power, biting hooks, and multilingual grit. Switching between English and Spanish, their sound channels classic punk urgency with a modern edge. Releasing demos, a live session, and now their debut EP, they showcase tightly crafted tracks that explore anger, identity, and resilience.
Brain BentSince debuting in 2020, Brain Bent has established itself as Calgary’s most reliably menacing synth-punk act. Their sound ranges from devolved egg-punk ditties to furious blasts of hardcore (as heard on their 2025 release, “No Signal”) with darkly sardonic, at times hilarious lyrics. Stretch before seeing their show; you WILL be moving, non-stop.
For over a decade, Calgary psych-pop wizard Ryan Bourne has lent his singular touch to projects like Ghostkeeper, Sleepkit and Chad VanGaalen. On 2023’s Plant City, Bourne recruited VanGaalen and Chris Dadge to co-produce a strutting garage pop odyssey. The five-piece Plant City Band brings this dream to hazy, dazzling life.
With evocative storytelling and a dry sense of humour, knitting makes guitar driven, lyrically introspective indie rock evoking the nostalgia of ‘90s alternative. Their debut album Some Kind of Heaven was released in September 2024 to international critical acclaim, leading to tours across North America, Europe and the UK. Their second full-length album is expected in June 2026.
Characterized by soft vocals and loud guitars, Montreal’s Fionavair draws inspiration from cold winters, lust, and bears. The indie four-piece blends elements of post rock, shoegaze, grunge, dream pop and more into a delicious little cocktail, and you can’t have just one. Check out their latest track “Neighbours” for a taste of what to expect.
Ever since 2016, BETABOYS has been celebrating ‘80s new wave and synth-pop music with infectiously party-ready energy. Their first full-length album, Great Pretenders, dropped last December and received regular radio airplay across Alberta. These dudes have a message of diversity, inclusion, and hope for a world where we’re all slow dancing to synthesizers.
