It’s that time of the year again when music lovers gather in a field to celebrate the thing they love, live music.

There are all sorts of festivals to cater for all sorts of musical tastes in all four corners of the world. The main ones kick off at this time of year and hecklerspray is here to tell you all you need to know about each festival, who the essential people are to see and which act to avoid so you can queue up for the overflowing shit-filled portaloos.

We begin with the first big festival-type affair of the year, this weekend’s Radio 1’s Big Weekend down in Kent. This particular bash doesn’t have a fixed location, but over the years it has proved to be a popular event for all who can get a ticket.
