The street festival attracts jazz musicians from across the world

Dyfed-Powys Police said they only had to make six arrests after Friday's opening day - believed to be the lowest number in the festival's 20-year history.

Most of the arrests were made for public order offences and one for a drugs offence.

The numbers attending the festival this year are expected to break all previous records.

More than 50,000 people descended on the small mid Wales market town last year but it looks as if the numbers will be even higher this year, according to festival director, Andy Eagle.

"The numbers have been great so far with ticket sales well-up on last year," he said.

"The number of people attending is definitely well over the predictions.

"We're delighted with how it's going, although it is too hot!" he added

Andy Eagle says ticket sales are higher than last year

The three-day festival has grown into a musical event of international stature and was voted one of the top 10 festivals in the world by Observer Magazine two years ago.

But despite its success, there are fears the festival could move from Brecon to a location outside of Wales because of a funding row.

Organisers claim it might have to move because Powys County Council withdrew an �11,000 annual grant towards the cost of the event.

Earlier this year, the festival was given more than �380,000 by the Welsh Assembly Government to secure its future.
