The Coruscant Opera was a favorite locale of Supreme Chancellor Finis Valorum (and, as a result, many other members of the Galactic elite). When Valorum's planned attendance at a showing became known, ticket prices automatically were raised astronomically.
Possibly the most prestigious and exclusive arthouse in the Galaxy, the building itself was built in a baroque design that predated the formation of the Old Republic and included an actual orchestra pit. The Opera's usual (ie, wealthiest) patrons could reserve private viewing balconies, with individua, levelled seating for the rest. However, the less fortunate could attend, in a way - the Opera included a group of built-in holorecorders which transmitted each performance live.
It was at the Coruscant Opera that the opera, The Brief Reign of Future Wraiths, was first performed in 33 BBY after returning to the capital from twenty years of touring.
Behind the scenes
The Coruscant Opera may have been intended to be the same building as the Galaxies Opera House.
