Isaac is a Native Hawaiian musician whose sound is rooted in kanikapila—the relaxed, “backyard” style of Hawaiian music built around acoustic instruments, group harmonies, and a mix of traditional and contemporary mele. Raised on O‘ahu, he credits his early love of music to his father and the tradition of kī hō‘alu (Hawaiian slack-key guitar) that was part of his home life.

In the Washington, D.C. area, Isaac became a founding member of The Aloha Boys, a group formed after the members met in 1996 while playing music for their kids at Hālau O ‘Aulani, a school of Hawaiian culture. Their performances emphasized tight vocal blend—often with everyone sharing lead and backing parts—paired with warm, acoustic arrangements that feel intimate and welcoming, the way kanikapila is meant to.

Isaac has performed widely at cultural programs and community events, and has been booked for special occasions (including weddings). Isaac plays guitar and ukulele in the classic Hawaiian style. His relationship to Hawaiian music—both as a cultural anchor and as a personal outlet—also appears prominently in the documentary Corridor Four, which highlights how music and family help shape his life beyond public service.
