The concert business will be decimated from a technical production standpoint. The artists still have a limited income stream when sitting on the couch. Their life style might downsize but they will eat. The promoters, when the business starts back up only need a phone, and a check book, assuming they have contacts and their expertise. One could guess there are 10-100 behind the scenes personnel currently out of work for every person performing onstage. They have normally no other income streams. We are talking audio techs/engineers. lighting techs, band techs, managers, stage hands, truck drivers, security, caterers, stage techs, set builders, pyro techs, video techs, riggers, electricians, bus drivers, parking lot workers, building staff/maintenance, etc. many of these people are attracted to the industry when in their younger years by the "bright Lights", and often as they age, and gain responsibilities among other things, they leave the industry. This sudden downturn will greatly IMO hasten that. Some of these techs are very bright and creative, and will venture into more typical 9-5 employment to enjoy time with their families.

I suspect the live concert industry might be the last industry to return(?) to Pre Covid days. That likely will not matter to most outside the industry. The companies that employ many of the above workers, are normally rather leveraged by the constant need to lease/buy always the latest new thing to stay competitive. Going beyond 3? months without income is not possible. There are very few other options for income with their equipment inventory. A very few of the heavy hitter vendors can survive, but they are way too pricey, inefficient cost wise, and not interested in servicing the regional concert industry upon a restart. Anyone thinking of investing $1,000,000+ to enter the industry to maybe turn a profit upon a restart is taking a huge risk, besides getting a qualified/trained crew together will be rather tough.

The world will go on without concerts, but it will be a different world.
