The Team

Adrian Ball – Director

My AV career started at school by operating the lights for the theatre performances on giant rheostat dimmer boards, this progressed into building speakers and lights for my mobile disco.
After leaving school I worked as an Electrical Design Engineer in Industry, in parallel with this in 2002 I created Hollowsphere by renting projectors and screens.

Joel Clements – Head of Live Sound and Lighting

Originally  starting out in a 2 inch tape recording studio I quickly developed a passion for all things technical. As a result for the past 15 years I have been lucky enough to work on a wide range of projects. These have included PA installation and FOH  operation, production and technical support, lighting and sound design for theatre. Some of the clients I have worked with include Manchester International Festival, Walk the Plank, Kendal Calling, Latitude Festival, 4D group. I am equally at home in a tent at a festival as I am in the control room in a theatre. I thrive on finding technical solutions in a creative environment.
