Owen Costello is a multi-talented artist, freediver, and musician currently based in Hawaii, having made the scenic move from his native Connecticut shortly before the global shifts of COVID-19. His life in the islands has deeply influenced both his musical expression and his profound connection to the ocean.

“Owen is a great entertainer. Awesome vocals, guitar playing, and smooth leads that blend perfectly with his creativity in building beats and loops. He’s also a talented songwriter. I’m very impressed with the catalog of songs he’s written. I’ve had Owen perform at my farmers’ market numerous times, and it’s always a pleasure when he can be there. I’d recommend Owen to anyone looking for music for any occasion.”

In his musical endeavors, Owen Costello is known for his versatile and evolving sound. While he previously explored the dynamic possibilities of live looping to create lush, layered soundscapes, his current artistic focus marks a deliberate shift. Owen is now dedicating his energy to mastering the intricate and expressive art of percussive fingerstyle guitar. This refined approach allows him to build rich musical textures and rhythms directly from his acoustic instrument, creating a more intimate and organic performance.

His musical journey began in Connecticut with his father teaching him his first chord, and over time, music became a source of healing and joy. His move to Hawaii significantly broadened his sonic palette, leading him to immerse himself in the soulful traditions of Hawaiian slack key guitar, drawing inspiration from local legends like Ledward Ka'apana. These influences, combined with his long-standing admiration for artists such as James Taylor, Peter Mulvey, and Chris Smither, shape a unique sound that transcends genre. Owen's compositions are a vibrant fusion of global philosophies, personal challenges, and diverse styles, from folk to funk, fingerstyle to bossa nova, and the compelling rhythms of his new percussive techniques.

Whether online via his ever-growing Youtube channel, or performing at bars, local farmers' markets or other venues across Hawaii, Owen shares his music with a powerful message: to inspire personal growth, encourage listeners to confront their fears, and embrace genuine happiness. Through his nuanced guitar work and heartfelt lyrics, Owen Costello invites his audience into a world where the tranquility of the ocean meets the expressive depth of a truly dedicated artist.

“Owen did a great job entertaining the crowds at our 15th Annual Misquamicut Beach Fall Festival, and I would highly recommend him for any event or festival! He is a talented and engaging musician.”
—Caswell Cooke, Executive Director of Misquamicut Business Association

“He came with all of his equipment and set it up seamlessly. He performed several original songs and built the production up from scratch using a loop machine in real time. We, the audience, thoroughly enjoyed the process and were impressed with the way he tied all of the sounds together before singing and playing guitar over the entire loop! What a treat!”
