The Kaau Crater Boys were formed in the early 1990s by Ernie Cruz Jr. (the son of Ernie Cruz Sr. and brother of Guy and John Cruz who are also local entertainers) and Troy Fernandez. According to Ernie's brother John, Troy needed a job to keep him out of prison, so he asked Ernie if he could be a part of his gig at Mooses Mc Gillycuddy. Ernie was reluctant at first, but because they knew each other's family, Ernie helped Troy out. This is how the Ka'au Crater Boys were started. Their first album, Tropical Hawaiian Day, was released in 1991 and marked the official beginning of Troy and Ernie’s 7-year partnership as one of the most successful groups in contemporary island music. Cruz played bass, acoustic guitar and handled main vocals for the majority of songs they recorded. Fernandez also played bass, contributed to vocals (mainly as a backing vocalist), but was mostly renowned for his musicianship with the ukulele. The creation of the Kaau Crater Boys also coincided with the resurgence in local Hawaiian customs and tradition, as well as promoting the renaissance of Hawaiian culture, especially among the local youth. As part of a collective of artists from the Palolo Housing area of Oahu, Cruz and Fernandez earned a steady gig at the Elks Lodge which also opened the door for Troy and Ernie to tour Japan for 6 months. A last minute appearance a few years later at Moose McGillycuddy’s Pub became a regular gig - this time as “E.T.,” “Ernie/Troy” (a play on names after the popular film, ET – The Extra-Terrestrial). The name Ka'au Crater Boys was actually a name that Ernie's brother John came up with years ago, Ernie asked John if he could use the name. Although John was hesitant at first, he allowed them to use the name. Ernie Cruz (father of Ernie Jr. and Guy) died in May 2016. Guy Cruz died in September 2016;
