Ed Sheeran’s three concerts are the first at the redeveloped stadium with some 120,000 tickets snapped up by fans.
“It’s a historic occasion,” Mr Aiken said.
“Ed has sold 405,000 tickets all over Ireland, including 120,000 in Cork. Nobody has ever done it in the history of live music in Ireland.
“It is also the first concert at the new Páirc Uí Chaoimh. We were here before with Bruce Springsteen, Michael Jackson and U2, but this is a totally different experience because the facilities are top class now.
“We have 40,000 people here each night and people are travelling from all over and it is looking like a great weekend.”
Mr Aiken books the biggest acts in the world to play in Ireland. Later this year, he is bringing the Rolling Stones, Elton John and Paul Simon to Ireland. For him, nobody holds a candle to Sheeran at present.
He said: “We are going to see, for my money, the best rockstar in the world. There are very people few people who could sell three nights in Cork.
“But this will be a great advert for Cork and Páirc Uí Chaoimh. All going well, there will be a concert every year in Páirc Uí Chaoimh going forward.
“Every hotel and guesthouse is booked out; everyone on the street is talking about it. Ed sold 405,000 tickets and he could have sold even more.”
Upwards of 200 contractors are hard at work, readying the state-of-the-art stadium for this weekend’s concerts.
It is the first stadium concert in Cork since Bruce Springsteen in 2013.
“There are more than 200 involved at the moment, readying the stadium for the weekend. There will be 1,500 people involved on the day, including our team, gardaí, medical, service staff and everyone else,” he said.
Stadium director Bob Ryan said the event is a major opportunity for Cork.
“For the GAA in Cork to have the facility to support an event like this is superb and it is very important for us that this goes well and that we will have more of these shows in the years ahead.
“This is the big experiment; if this goes well — and everyone wants to make a success of this — we would be happy to.”
