Should orchestras formed for an annual music festival have different artists (eg, Festival Orchestra 2017, Festival Orchestra 2018,…) or have one artist but with its musicians use end dates to denote when they were part of the orchestra?
I don’t know if there is a rule covering it, but I would (and have) just listed it as the orchestra name. The year is the year of the event, not the name of the band.
I suspect that a popular festival orchestras will eventually need to be divided into years as the numbers of members/former members will continue to grow and the exact composition of a specific year’s orchestra may become of interest and will need to be presented in nice neat groupings.
I don’t think I’ve ever seen an orchestra with more than a handful of linked members anyway. That information is simple not available most of the time.
I would prefer having a single orchestra, rather than a new one for every year.
By the way, it would be great if on the relationship page, you could set a date range and only show relationships that fall in that range.
The other thing to consider is the EVENT section.
If someone wants to know who played and what they played at the 1999 festival, they could open the event list to see.
