Getting your band onto the radar of festivals

[lanark]

How's it done? Do you write to them? Do they find you? Do you need an agent?

I'm thinking especialy the bigger ones that are full of small bands filling in time between the big acts.

Also what's the pay like? A decent fee? Just free entry? Not even that?

Wondering, cos I'll be visiting WOMAD this year and was curious as to how places like that and Glasto fill up their roster of acts beyond the big names.
