High school music competition Smokefreerockquest celebrates its 25th birthday when it kicks off this weekend.
And founders Pete Rainey and Glen Common, who still run the competition, have seen many changes since they put on their first event in 1989.
Back then the majority of the bands played covers (now the basis for the competition is original music) and this, together with advancements in technology and a big shift in young people's attitudes, has resulted in a far wider range of musical genres.
"The definable [music] styles have gone and kids are genre-busting and attempting to come up with their own unique sound," says Common.
"That said, metal endures - it's like cockroaches after a nuclear attack - it never really goes away."
