ReVaria Orchestra Collaborates with ACA Insurance's Choir for 70th Anniversary Celebration

Euphonia Music Production is back on the corporate stage. ReVaria Orchestra performed at ACA Insurance's 70th anniversary celebration on August 31, 2026, at Shangri-La Ballroom, Jakarta — this time collaborating directly with ACA's internal choir in a single orchestral performance.

Rather than simply filling a slot on the program, ReVaria stepped in as musical director, bringing ACA's choir onto the same stage as its own musicians. Professional players and the company's in-house singers performed side by side, delivering several songs in full orchestral arrangement throughout the celebration.

The collaboration was prepared through joint rehearsals at Montrion Music Academy ahead of the event. Aligning the musical feel between an orchestra and a non-professional choir takes process — it's not something a single run-through can achieve. Rehearsing in the right space also gave ACA's choir room to build confidence before performing in front of invited guests.

For ACA Insurance, involving an internal choir meant employees weren't just an audience at their own company's celebration — they were part of the performance. That's where ReVaria Orchestra's role became essential: bridging the employees' spirit with a level of musical quality fit for a stage like Shangri-La Ballroom.

ReVaria Orchestra is an orchestral unit under Euphonia Music Production, a music ecosystem that also oversees Montrion Music Academy and HalloHEXA. This experience reaffirms Euphonia's position as a reliable music partner for corporate events with high scale and high expectations.
