Brother Iz is great. My favorite group is Hapa (seen them many times), Nathan Aweau, Keali'i Reichel, many more. I listen to Hawaiian 108. You can stream it online. Cecilo and Kapono, Brothers Kazimero, (my spelling is off I'm sure). Many amazing musicians play in Waikiki, and some in Kapolei from time to time too (and at Aulani). It amazed me to be at the Moana and hear someone I listened to on the radio.
