Athens Rocks festival organizers just sent this press release, concerning the 2020 edition of the festival and its cancellation:

"When we announced AthensRocks 2020, we surely did not expect that we would have a summer without concerts.
 
However, the unpleasant developments brought by the pandemic, as well as the government’s announcements, lead us to the postponement of this year’s edition of AthensRocks, which will not take place on June 14th 2020.
 
We are in contact with the artists that would perform at the festival and very soon we will announce its new date for 2021, as well as information regarding ticket holders.
 
We ask for your understanding and patience regarding any delay that might occur, due to the unprecedented situation we face.
 
We respect your support, thank you for your trust and work in order to reciprocate!
 
We would like to express our solidarity and support to everyone who works with us in concert production and generally in the show business, since they are confronted with an unknown professional future and we request from the state to act accordingly and take measures immediately to protect the industry.
 
The show must go on! The concerts and festivals we love do not end here. We’ll meet again side by side, in front of a stage and our favourite band will ask us to sing louder, with all the strength of our soul! We keep on listening to music, so that apart from safe, our lives are more beautiful!
 
Stay safe & Keep on AthensRocking!"

So, this year's Athens Rock fetsival (The National, Idles, 14/06/2020) will be cancelled.
