Square Enix have announced the first ever official Final Fantasy VII orchestral concert, "Final Fantasy VII - A Symphonic Reunion", to be performed at the Dolby Theater in Los Angeles, California, on June 9, 2019. Tickets went on sale today, and though the $77 tier tickets appear to already be sold out, tickets are still available at the $119 and $139 tiers.

Here's hoping for more concert dates and venues to be announced soon.

I hope they announce more dates, really excited for this.

There’s been a lot of people unhappy with Wild Faery but I can’t say I’ve had any major issues using them for 4 or so concerts now over 5 years (3 KH, 1 Piano Opera FF). Take that with a grain of salt. A lot of people are having trouble getting refunds, tickets, communication, etc. they could definitely do better and find a better seller, Wild Faerys web presence is awful.

No wonder there haven't been any other concert dates announced - according to attendees of the LA show it was a sad cash-in of a concert, with no new arrangements and around half of the show being video trailers and the synth OST played over speakers.
