Hawaiian music comes to the mainland at the 2025 Southern California Slack Key Festival.  Taking its name from a finger-picking style of guitar playing indigenous to Hawaii, the Slack Key Festival brings the art of ki ho'alu guitar to Redondo Beach.

The Southern California Slack Key Festival takes fans on a Hawaiian musical journey showcasing GRAMMY-winning slack key guitarists, the best hula dancers in the world, and special guest performers. 

This year’s Southern California Slack Key Festival’s line-up includes special guest Natalie Ai; George Kuo, Sonny Lim, Jeff Peterson, Jim "Kimo" West, Kamuela Kimokeo, Anuhea Lim & more to be announced.

In addition to the concert, the Island Fair marketplace – free and open to the public – takes place from 11am to 4pm outside of the venue. Visitors can browse a variety of island themed gifts, home décor, accessories, apparel, Hawaiian food, authentic island-style shave ice and outdoor entertainment.
