Sometimes referred to as "Pi" - Mr. Paul Inge is an accomplished musician and performer and is now (since 2014) the FOH Engineer (The "front of house" engineer focuses on mixing audio for the audience) for AURORA and the band! He can be seen in many group photos of the band when they're off stage or traveling.
