Kill the Colossi started playing in 2015 and started gigging alongside NBQ label mates The Mistakes and the Crash Landings at the beginning of 2016.
In 2015 KTC recorded an untitled E.P that was distributed digitally only. This E.P would set the foundations of their sound.
Towards the end of 2017 an album was recorded, mixed and produced by Gareth Matthews. Herd Mentality is available on CD now.
As of 2018 KTC move forward as a three piece.
