Um, direction of airflow, by definition, doesn’t affect the ballistic transmission of anything. On the other hand, the longer something hangs in the air, the more it’s affected by the direction of airflow, and that applies all the way down to gas molecules.
Singing or breathing hard seems likely to increase droplets of all sizes right down to submicron.
My prediction is that (1) it will be 2021 Summer before we see and hear the next festival, and (2) everyone will be required to wear face masks. Lastly, (3) Ravers won’t realize any difference.
