Country singer Nathan Carter says he cannot understand how GAA events can go ahead, but outdoor concerts cannot.
He was speaking as Taoiseach Micheál Martin said a roadmap for re-opening all sectors of society will be published by August 31st.
Mr Martin said he understands the frustration for sectors like live events that have not been able to open yet, and they will have clarity soon.
"We will be, over the course of the next week, working obviously with public health advice [and] all Cabinet colleagues in terms of preparing a roadmap - as we said we would at the beginning of the month - for the next phase of the management of COVID-19.
"And also in terms of a comprehensive roadmap for that next phase and for re-opening further sectors of society."
Nathan, who is due to play an outdoor concert in Derry this weekend to some 2,000 people, told Lunchtime Live he is very disappointed at the slow movement.
"I'm doing a gig this weekend up in Derry, an outdoor festival, and there seems to be no issues in the north of the border.
"So I don't understand why we can't get some sort of clarity or some sort of direction, or just even a date to work to.
"At the end of the day the entertainment industry was the first to close due to COVID, and now it's the last."
He says he cannot see the difference between sports stadiums and music stadiums.
"It's very frustrating, especially when you see the like of GAA events happening and sporting events happening.
"If people are allowed to go to them, what's the difference?
"In my view I don't see that much of a difference if you're allowed to go and watch that sort of event rather than watch some music in an outdoor setting.
"Especially if everyone [is] following the rules with masks and they've had the vaccines and so forth.
"Surely it can work if people are sensible about the whole thing."
'Gigs across England and Scotland'
The 'Wagon Wheel' singer says he has concerts lined up in UK for next month.
"We've gigs all across England and Scotland in September and there's no issue there.
"I'd imagine you have to show some sign that you've had your double vaccination and all that - which is totally right.
"But if it can happen there, what's the difference - I don't see the difference."
Nathan believes the entire industry has been unfairly treated.
"It's not just singers involved in the whole business - it's musicians, it's lighting guys, sound engineers, truck drivers, crew, promoters, managers... I just don't think the industry is being treated fairly at the minute".
On Wednesday, the director of MCD Caroline Downey said she had no faith in the Government to restart the events sector - as NPHET is running the country.
She told The Hard Shoulder she believes it is not Arts Minister Catherine Martin they should be speaking with.
"I do feel sympathy for Catherine Martin and the predicament that she's in, but right now I 100% believe our country is being controlled and run by NPHET.
"And actually the person who needs to be stepping up the plate here is Stephen Donnelly, and Leo [Varadkar] and Micheál Martin.
"And that basically NPHET stops running us, stops running our country, stops running our business and that they start focusing heavily on it."
"I actually have no faith in this Government.
"I don't know if it's because it's a coalition, but no decisions have been made.
"And the people who run this country is NPHET, and NPHET is there to actually protect the hospitals - so therefore care nothing about our industry", she added.
