Remnants of a website here. I stole all the info from there as I did not see them play personally.
Kayjun formed in 1996 on the foundation of strong friendships between all members of the band. Kayjun was the first band for each of the members, and in the early days found its feet by playing covers of their favourite bands, like Metallica, Black Sabbath, AC/DC and the Screaming Jets.
Kayjun’s early performances were enjoyed by all, and within months the band began playing at parties for friends and strangers alike.
After almost a year of playing covers, Kayjun decided that their musical future lay in writing and performing their own songs. In late 1997 the song-books were cast aside and the long, hard road of original song writing began in earnest.
Kayjun were the “most popular band” at Gozzy Rock, an annual, regional band competition, in each of 1997 and 1998, and were also the overall runner-up in both years.
Kayjun were semi-finalists at the statewide Next Big Thing competition in 1998. This competition is open to music of all types, and Kayjun were commended on their performances by judges of wide musical persuasions.
Kayjun were one of four nominees for Perth’s Best Original Heavy Metal Band in the 1999 WAMI awards.
They called it quits in 2001 and guitarist Anthony Wong went on to play axe for Syzygy.
Here is their EP ‘Storm’. Release date uncertain, I think around 1998 or 1999.
