The festival mainly maintains several-day outdoor event format.
As the organizers of Tbilisi Open Air clarify, the defining idea behind the festival is freedom.
That broke the previous record and TOA 2022 became the most attended commercial music event of all time in the history of Georgia.
The festival showed heavy support to Ukraine in the Russo-Ukrainian war that broke out that year - through donating part of the ticket and merch sales to the Ukrainian cause, supporting Ukraine through all media and communication channels, inviting pro-Ukrainian acts, etc.
In 2019, TOA was held on the Lisi Wonderland field and went on for 3 days, with 4 stages operating.
In 2017, TOA was held on Lisi wonderland and had 3 day lineup with around 40 artists.
This was by far the biggest musical event which has ever happened in Caucasus or Middle Earth and the festival broke all records in social media, having three times bigger feedback than in 2013.
Although criticized for smaller line-up compared to former years, the organizers announced this was "a decision essential to switch back to the fields and prepare for 2015, which should be the biggest event both by line-up and scale".
With Deep Purple as headliner, the line-up was the biggest happening in the region and received a lot of local and foreign media interest, especially from Armenia, Russia, Turkey and Azerbaijan.
Despite this, after the event the organizers of the festival stated their opinion that Tbilisi Open Air belonged more to outdoor fields than Stadiums or any kind of buildings.
"We received invaluable experience, but the heart of the festival stays with the fields" - stated organizer Achiko Guledani - "next time we will try to accept the challenge to bring even bigger line-up there."
Headliner of the festival was a legendary Russian band DDT, which caused a lot of local interest.
Total attendance was over 50 000, which remains as a record not only in Georgia, but in whole Caucasus region.
The 2009 event was held in Tbilisi, on Sharden Street (15 May) and on local hippodrome (16–17 May).
As it was the first big happening since 1980 Tbilisi Rock Festival, the festival was covered by foreign media: Times Online, Reuters, El Mundo, Corriere della Sera, Associated Press, Nouvel Observateur etc.
It served as an important simulator to the local music business and caused a boost in the numbers of new artists.
In 2012 Tbilisi Open Air started allowing tent camping as an option for festival lodging.
Tbilisi has mostly welcoming weather in summer and the same holds true for the event.
Tbilisi Open Air is run by Altervision Group which mainly consists of former and active musicians/producers.
The first concept of the festival was created by Achiko Guledani, Vaho Babunashvili, Irakli Nadareishvili and Beqa Japaridze in 2009.
Nowadays the decision making board of Tbilisi Open Air consists of 7 people.
