Twin Fin formed in 2020 when longtime friends Robbie Kelly (vocals, rhythm guitar) and Tyler Schiller (bass) relocated to Oahu, Hawaii, initially jamming in post-surf backyard sessions on the North Shore. The band, completed by Zack Wilson (lead guitar) and Chase GiGregorio (drums), is based in Honolulu and plays rock music. They have performed locally on Oahu since around 2021, developing a following through live shows. Twin Fin is known for energetic live performances that capture the vibrant surf and island atmosphere. No major albums or awards are documented in available sources.
