There has been a lot of talk about the prospect of live music returning on a large scale in 2021, but right now, at least, it's hard to imagine that happening.

However, one recent trial concert that took place in Spain has raised the hopes of a lot of music fans.

The Primavera Sound festival conducted a test at Barcelona's Sala Apolo venue on December 12th. Attendees to the gig - which featured two live bands and two DJ sets - were between the ages of 18 and 59 and none of them had received a Covid test in the two weeks prior to the gig.

On the day of the gig, each person was given a rapid Covid test and received a negative result within 15 minutes. 463 attended the gig, while a control group of 496 were held back from attending.

Each attendee was given an N95 mask to wear, and even the bar (a separate large area to the venue) was open with improved ventilation; the only time that people could remove their mask was to drink. Bathrooms and smoking areas were monitored for capacity, but inside the actual venue space, there was no social distancing enforced.

The good news? After being re-tested eight days later, none of the 463 people who had attended the gig had developed Covid. 2 of the 496 control group tested positive.

Researchers told NME: "That was, precisely, the objective of this study: to validate these kind of tests as an extremely useful tool to be able to carry out any type of event, whether musical or not, without social distancing."

Rapid testing and masks at well-ventilated venues may be the way forward, at least in the forseeable future - but would either of those conditions put you off attending a gig?
