What have been your 'discovereies' from the line-up so far? Stuff that hadn't really passed your radar but you'll definitely be checking out come August. Last year for me it was Treefight for Sunlight, Michael Kiwanuka, Cave Singers and Cowbois Rhos Botwnnog.I guess at least half the new music I come across is via Green Man (the other 50% is probably from Marc Riley). I came across King Creosote, Efterklang, Caribou, Race Horses, Fanfarlo, Caitlin Rose, Erland and the Carnival etc etc through Green Man, not to mention some real gems that seem to have disappeared like Monkey Swallows the Universe, Gilbert and 6 Day Riot.
This year, so far, Dark Dark Dark, the Felice Brothers and Tiny Ruins have all moved onto my must see list (of course I have a bloody list).
Conversely, anything you'll be avoiding at all costs? That'd be Rocketnumbernine, Three Trapped Tigers, the Walkmen and Gang Colours for me.
