Music venues, theatres and their workforces have taken part in a day of action around the UK to highlight the crisis facing the live events scene.
More than 300 venues including London's National Theatre and Royal Festival Hall turned their lights red as part of the Red Alert campaign.
And out-of-work music industry crew were among those who took part in a march through Manchester on Tuesday.
Peter Gabriel, Imogen Heap and The Cure have voiced support for the initiative.

The Red Alert movement and #WeMakeEvents marches aimed to raise awareness about the threat of job losses in the sector.
Producers, engineers, tour managers, security staff, truck drivers and cleaners also marched past some of Manchester's closed venues.
Similar protests took place in other cities, as arts and event venues were illuminated to highlight the Red Alert theme.

The Wales Millennium Centre in Cardiff gave a shout out to all the "amazing staff and freelancers in our sector who bring the live events we love to life".
Some of Scotland's most famous venues, including King Tut's Wah Wah Hut - where rock band Oasis were discovered - also went red for the cause.
Bands including New Order and Doves put their weight behind the Red Alert movement.
"Without major immediate support from the Government, the entire live events sector supply chain is at risk of collapse," New Order posted.
Wembley Stadium, England's national football stadium and a gig venue, declared that it was "proud to support our music industry in its time of crisis".
Virtually all UK venues have been closed for five months, putting many at risk.
Organisers of Tuesday's protests said around a million people work in the events sector, many of whom are freelancers, and they are in danger of losing their livelihoods without additional government support.
'Everything went off like a light switch'
Freelance audio technician Alistair Westell had been booked for several events around the world before the coronavirus outbreak.
"For me personally, everything in my diary popped out in March, including the Olympics in Tokyo, which I should have been working at last week," he told BBC News. "I'm used to quiet spells, but with this everything went off like a light switch. [Most events] have been pushed back until next year, if at all.
"I must admit, I've had a few sleepless nights. Luckily, I have a partner who is still working, but the money I'm living on is savings, so it's affected us quite badly."
Westell explained that freelancers and venue staff are crucial to an event's success, even though they "aren't very visible".
"We're often behind the scenes - if we're seen it usually means something has gone wrong!" he said. "We try to stay in the background, and that's one of the reasons we've been forgotten."
The work involved in putting on a live event such as a concert or conference is "a huge team effort"," he added.
"There's lighting, graphics, sound, video, rigging, staging… and then you've got the other side of it - the toilets and the catering for the audience, artists and crew. Then there's security - you often see security staff pulling people out of the crowd at the front when they're in trouble."

On Tuesday, the Arctic Monkeys announced a Crowdfunder campaign to raise money for The Leadmill in their home city of Sheffield and other venues.
Nightclub and festival promoter Sacha Lord, who is Night Time Economy Adviser for Greater Manchester, said work by many crucial events staff goes "unseen by the public".
"From my own experience with [music festival] Parklife, there are about 4,500 people working on that," he told Radio Manchester.
"The stages don't erect by themselves, the Portaloos don't arrive by themselves, the fences, the arenas, the lighting techs, it is a vast swathe of freelancers that work behind the scenes, and sadly they have been forgotten.
Singer-songwriter Peter Gabriel said: "A lot of high arts have now been given some support, but people working on the festival side of things and in live events have been forgotten about.
"Many of these people are freelancers so don't fall under furlough schemes. So right now they are feeling the pinch very badly."

The furlough scheme and support for self-employed people are due to end in the coming months - and many freelancers were not eligible for them at all.
"Without major, immediate support from government, the entire live events sector supply chain is at risk of collapse," said the members of The Cure in a statement.
"The aim [of the campaign] is to have financial support extended for the people and companies in this sector, until they can return to work."
