The first official setup of the stage took place on June 7 (to 17) on the Plains of Abraham park (historical site), where the festival runs. Since then, the stage hosted performers Bruno Mars, Stevie Wonder, The Black Keys, Def Leppard, Rush and many others during this 11-day festival (between July 4th and 14th) and more recently those of Paul McCartney, July 23, and Celine Dion, on the 28th.
According to Patrick Martin, Production Manager of the Festival: “We really needed to expand our main stage (Bell stage), to improve its technical capabilities while increasing safety. Unisson has presented an innovative concept meeting all these criterias”.
For Olivier Jobin, Vice President of Unisson structures: “We are proud to offer so far, the stage with the highest degree of technological achievement. Working with the leaders of the Quebec City Summer Festival expertise, we have been at the heart of the issues of our more sophisticated customers. “
