"We think that any festival that our target audience would go to would be proud of the bill that we have pulled together." p> He added that the build-up for the event had been smooth.

"The last time we did one of these earlier this year in Manchester we had torrential downpour on the week leading into it, but no such problems in Cardiff I can report," he said.
