Flourish and Decay included covers 'Who Killed Mr. Moon Light' (Bauhaus) and 'Papa Was A Rolling Stone' (The Temptations). The Wellington filmmaker Richard Gibson won the 1990 Flying Fish Video Award for Trasch's 'Half Man Crazy' from the Flourish And Decay album.

In 1991 Andrew Armitage offered their second, self-funded, album to Wildside Records to release. The group's first single for the label, 'The Reason Rhyme' (on cassingle only) was released early in 1992. The video for the new single was once again made by Wellington filmmaker Richard Gibson with the benefit of an early NZ On Air video grant. 

Eyes opened very wide when Arthur turned away from the audience, revealing that his leather pants were incomplete.

Early 1992 Mike Young moved to Auckland to work for radio station 89X. The single 'The Reason Rhyme' achieved the No.5 position on 95bFM's "Alternative Top Ten" on April 15, 1992 after seven weeks on the listener-voted chart, just as their debut CD album Chemikaze was released by Wildside. The single 'Reason Rhyme' was also released in Australia on Wildside, via Festival Records on March 16, 1992.

In an unusual move, Trasch's Auckland appearance was with rock bands Rumblefish, Second Child and 7 Dials at Ponsonby's Gluepot on Friday March 20, 1992. Trasch's performance that night won over the Gluepot crowd but eyes opened very wide when Arthur turned away from the audience, revealing that his leather pants were incomplete.

"Arthur will dress outrageously to give people something to look at and we just put a lot of energy into it," Mike Young told RipItUp (April 1992). "I think people are surprised by how much energy a keyboard band can have."

When Trasch played Wellington's Paisley Park, they called the venue to say they'd be an hour late as they'd been in an accident. "They announced it over the PA and everybody said, 'oh no'," said Young. "We'd been with a friend of ours who does latex makeup for films and we turned up with open cuts and gashes all over our faces and Arthur's bald head had a bit of brain poking out."

Young reflected on their recording process: "We'd sample a whole riff rather than a sound and then fuck around with it so it sounded completely different. On Chemikaze we didn't want to be machine music so everything's played manually – so some things go out of time."

"The vocals, Evan's and Arthur's turned out quite masculine, quite butch," said Young. "That's probably because of the way we record them, do heaps of processing, squash the sound up so it's really condensed and then do about 10 tracks singing the same thing, so it sounds like an army of people. Front 242 are like that – you can imagine an army of people singing."

In 1995 Evan Roberts remixed two Shihad tracks that appeared as bonus tracks on the CD single 'Gimme Gimme'. They were ‘Silvercup’ (remix) and ‘Clapperloader’ (remix).

Trasch ceased to function when vocalist Arthur Tauhore became unwell. He died on 28 November 1993 of an Aids-related illness.
