Featuring: Raymond Kane, Sonny Chillingworth, Ledward Kaapana, Leonard Kwan, Haunani Apoliona, Diana Aki, and George Kahamoku Jr.
This compelling look at Hawaiian slack-key guitar unveils a cultural richness that is uniquely Hawaiian. The story is told not by a narrator but by the artists telling their stories in their own words so that the spirit and feeling of the Hawaiian people emerge. The development of slack-key corresponds with Hawaiian culture while preserving its tradition in form and verse. This film, with its infectious musical aspects that are specifically Hawaiian, couples with its rich visual material and varied sequences, is an important documentary of Hawaiian culture to share with contemporary audiences."
