They are one of the biggest rock bands in the world, but Sydney has served up a shock to U2 - their second show, last night , has not sold out. Check out the setlist details.

More than 2200 $40 tickets - the cheapest for the Irish band’s 360 tour - are unsold for concert at ANZ Stadium. Limited tickets are also available for more expensive seats, promoter Michael Coppel said.

He said that may be because the unprecedented number of concerts this summer has saturated the Sydney entertainment market.

Mr Coppel, who is bringing other popular musicians such as Linkin Park, Katy Perry and Rihanna to Australia, said he has “never seen the Australian market this busy”.

“Seven national tours that have gone on sale in the last five days,” he said, naming Justin Bieber, Santana, Lionel Richie and James Blunt.

“I think it reflects the fact that when they [U2] toured last time, when their tickets went on sale, there were very few other concerts on sale.

“When they toured this time, they were the last big show of the summer to go on sale, and there was substantial sales already to Bon Jovi, and the Eagles, and Leonard Cohen and Muse and a range of other shows.

“Obviously everybody’s business is slightly affected because we only have a limited amount of people.”

Mr Coppel said one of the reasons that rival promoters had scheduled their concerts all around the same time was that each of them was busy working on their own projects and weren’t aware of what their competitors were doing until they reached the promotional stage.

“Every promoter, if they are honest, would say ‘I didn’t realise it was going to be this busy. Suddenly there are 22 on the market.’”

The cluttered calendar was expected to free up by next winter, as it usually does, and as promoters reassess the number of acts they are bringing in to Australia, he said.

“Hopefully it will be a little less frantic in the summer next year.”
