Brecon Jazz Festival attracts up to 50,000 visitors

Organisers say it is on course to be one of the most successful weekends in the event's history, with ticket sales up 10% on last year.

However, Dyfed-Powys Police have urged festival-goers to act responsibly this weekend.

They have warned that any anti-social behaviour will be acted upon.

A total of 95 acts will entertain the crowds at a variety of venues including Theatr Brycheiniog, Watton Marquee and the Market Hall.

Festival spokesman Tim Powell said: "We're expecting a very successful weekend.

"Tickets sales currently stand at 15,000, 10% up on last year.

We have fixed penalties this year and people could be issued with �80 penalties for public order offences Chief Inspector Steve Hughson

"There really is something for every jazz lover at the festival."

Dyfed-Powys Police urged festival-goers to act responsibly this weekend.

Chief Inspector Steve Hughson said: "We want people to enjoy themselves at the international festival of jazz.

"But we want them to act responsibly when it comes to alcohol.

"If there are incidents of anti-social behaviour we will not hesitate to act swiftly.

"We have fixed penalties this year and people could be issued with �80 penalties for public order offences and �40 for drunkenness."

Festival organisers said there was no trouble at the Super Furry Animals' sell-out concert on Thursday.

Gruff Rhys referred to the petition during Thursday night's show

"The police were pleased and the concert was a great way to kick off the festival," said Mr Powell.

"The market hall was a great venue and underlined what a great place it was for that type of act."

The Super Furries' show had initially been planned for Brecon's Watton Field, but residents living nearby complained last month that the venue was not suitable due to concerns over noise.

Singer Gruff Rhys told BBC Wales that it was "like a dagger to the heart, we've had a petition to try and stop us playing and the mayor's complained".

Mr Powell added: "Gruff Rhys did make reference on stage to the petition that was put up against the band's concert.

"He said something along the lines of, 'we beat the petition.'

"And he also commented about comments made about drugs and rock and roll, saying that there are a few stories about drugs and jazz musicians.

"He added that the band was in town to clean up the jazz festival. His comments went down well with the crowd and were meant in good humour."

Gruff made his stage entrance in a crash helmet and later ate an apple while singing on stage.

The band received the biggest cheer of the night for their song Herman and Pauline.

The weekend's events start on Friday night with a concert by musician Claire Martin.
