HGA Creative Communications has been appointed to deliver the soft drinks manufacturer's event, which takes place on 25 March, for the 12th consecutive year.
The agency has worked with the Irn-Bru manufacturer for nearly 20 years on a range of live events, video, digital and design projects.
HGA will look after all the technical staging and production of the event.
"The relationship we have with HGA is one born of complete trust and understanding with our business. When you add the creative flair it brings to the event, it really is an exciting partnership," said an AG Barr spokesperson.
