Koastle

Two wise-cracking friends who seem real cool to share a beer and some laughs with may seem unlikely heroes of the future bass revival, but behind Koastle’s approachable humor and laidback demeanor lies a striving dedication to golden hour sounds that elevate the soul.

Since meeting in college and growing close through a shared love of ODESZA and Flume, Andy Mueller and Brett Beaudette spent 10 years perfecting the Koastle sound. It’s an uplifting, energetic and nostalgic style, mixing wonky future bass beats with bittersweet chords, glittering synth textures, gritty bass bursts and romantic feeling.

With a catalog that boasts more than 50 million cross platform streams and viral social media moments, Koastle leads the indie-electronic revival. “Out of Bounds,” “Hurricane,” “Stay Close” and a remix of Lorde’s “What Was That” infuse the spirit of 2010s future bass with modern technique. On stage, Koastle’s vision comes to fruition in an immersive, one-of-a-kind experience touted as one of the best live electronic shows on the up and coming scene.

All this growth is reflected in Koastle’s debut album In The Beginning. Released in 2025, its 15 deeply-personal tracks aim beyond the viral-hit machine to create a foundation of world-building for a far-reaching career. “We don't take ourselves seriously, but we take our art very seriously,” Mueller says, and it’s that mix of warm-hearted inclusivity and dramatic artistry that makes Koastle fans feel they’re part of something grand.
