Initially, Cog played instrumentally, but after failing in a search for a vocalist, Gower took up the role, though without any previous experience.
In early 2003, Gower contributed vocals to the track Perception Twin by peers The Butterfly Effect, appearing on their Begins Here album.
After its release in April 2005, the album saw a slight shift and a massive growth in the band's fanbase, in accordance with a more commercial sound, while retaining a progressive feel, some tracks topping 10 minutes.
On 24 April 2013 Flynn and Luke Gower released a new single "I've been thinking" under a project name "The Occupants Music", recorded late 2012 at Rocking Horse Studios in Byron Bay.
[2][3] [4] In 2021, Flynn Gower stirred controversy after sharing posts of anti-vaccination rhetoric and conspiracies surrounding COVID-19 on social media, while also publicly voicing his support for the anti-lockdown protests in New South Wales.
[5] His vocal style is intriguing and unique, particularly in the early stages of Cog's development, alternating between a bizarre high-pitched semi-falsetto sung from the throat and more masculine timbres.
Gower's style is fairly left field, with a lot of contrast between heavier and lighter timbres.
In Cog, where rhythm plays a significant part in the music, there is usually a lot of interplay between drums, bass and guitar.
