Owen Costello is a versatile multi-instrumentalist, singer-songwriter, and freediver now proudly based in San Diego, CA. Born in Connecticut and deeply shaped by years spent living and performing in Hawaii, Owen’s music is a soulful reflection of the ocean’s tranquility and the diverse cultures he has encountered.

While previously recognized for his intricate live looping soundscapes, Owen’s current artistic focus is dedicated to the expressive art of percussive fingerstyle guitar. Blending this rhythmic acoustic mastery with influences ranging from Hawaiian slack key (inspired by legends like Ledward Ka’apana) to folk icons like James Taylor, his sound crosses genres—fusing folk, funk, and bossa nova into an intimate, organic performance.

Whether sharing content with his global audience on YouTube or performing live across Southern California, Owen’s music carries a powerful message of personal growth, resilience, and genuine happiness. He is thrilled to continue planting roots in the local music scene, including making his highly anticipated debut performance at MiniFest.
