Belgium's second largest music festival, which manages to pack in tens of thousands of alt-rock and pop fans into a pretty woodland enclosure, celebrates its 26th birthday. Among its many appeals – which include strong Belgian beer, a whose-who line-up – festival goers get free train travel from Brussels. The line-up has yet to be announced, but you can vote on the website now for who you'd like to see there and they'll aim to get a handful from the top 10 to show. Ticket prices are yet to be announced too. See www.pukkelpop.be for more info.
