Numb Ear Audio is a sound production and artist tour management business created and operated by Kalen Kerswell. It exists to allow local Australian artists to grow, develop, and thrive without abandoning the DIY ethos rooted within the alternative music scene. This mission stems from Kalens passion for punk, hardcore, emo, indie, and alternative rock music and the scenes built around these genres. This passion is ingrained within the foundation of everything he works on relating to Numb Ear Audio (which is named after southern California based screamo band Knumears) as well as his own music such as his hardcore band Non Kompliant.

Kalen is currently studying at JMC academy in Sydney, working towards a double bachelors degree in Audio Engineering and Entertainment Business management, rapidly expanding and developing his skillset and network.

So far Kalen has been lucky enough to work with bands across a variety of genres including indie band Between Two, punk bands such as Smokers Cough and Albanian Blood Pantree, and hardcore bands such as Non Kompliant.
