That Petrol Emotion was a Northern Irish, London-based band with an American vocalist called Steve Mack. The band evolved from the Derry Hitmakers and The Undertones. It was formed by guitarist John O'Neill and second guitarist Raymond Gorman who DJd together at the Derry "Left Bank" club. The band was completed by Damian O'Neill (bassist from 1985-1988 then guitarist from 1988-1994) along with drummer Ciaran McLaughlin and bassists John Marchini (1988-1991) and Brendan Kelly (1991-1994). From 1985, the band released a number of singles and full length albums. Even though they charted seven singles in the UK, they never improved on their first chart hit "Big Decision" in 1987 which reached number 42. They did, however, reach the Top 40 of the UK Albums Chart with the album Babble which was also voted one of the albums of the year by Rolling Stone magazine critics[1]. They also reached number 1 in the UK indie charts with their albums Manic Pop Thrill and Fireproof. The band's sound evolved over the years from John Peel-approved heavy indie rock on Manic Pop Thrill and Babble, to melodic indie pop rock after John O'Neill's departure on the albums Chemicrazy and Fireproof, via dance and sample experimentation on End Of The Millennium Psychosis Blues. Many believe that this diversity alienated people in the contemporary scene and so, That Petrol Emotion are considered very much before their time and pioneers for Britpop and crossover bands such as The Stone Roses, Oasis, Blur and Radiohead[citation needed].
