Tyler, I can't answer specifically for Pyrotecnico "Rock Loves", but it happens that a given show is done more than once, though some adjustments are needed for the length of the show and the particular features of the firing area.
For instance, Brézac Artifices presented in the 2006 Montreal competition a show which was basically the same than one displayed two years before in Cannes. The display was improved and adjusted for the size of Montreal (i.e.: the addition of 5 minutes to reach 30 minutes), but it was basically the same. (The designer Dominique Brézac answered to a specific question on that point in this
PyroPlanet report.)
To design a pyromusical display means a lot of work. Last week, a well-known Canadian pyrotechnician told me that it would take 3 or 4 years to him to achieve a brand new 30-minute show. Owing to that cost, it is just rationale for them to increase the benefits as much as possible.
