As the tens of thousands who’ve flocked to Great Stage Park for this years Bonnaroo Music & Arts Festival settled in for their first complete day of festivities, the event began to show its true breadth, opening all of its stages to welcome a massive range of music, cinema and comedy before closing the night with one of the worlds most revered modern rock bands, Radiohead.

Day one spilled over into overtime with a 2am sing-along screening of the R.Kelly parody “Trapped In The Closet,” sending those too amped to sleep back to camp on a song-and-laugh laced high.

After a good nights sleep the music restarted after lunch with The Kooks at Which Stage. Needtobreathe, Afrocubism, Feist and Foster The People occupied that same stage throughout the day while neighbouring tents played host to the likes of Two Door Cinema Club, Michael Kiwanuka, Trampled By Turtles and Ludacris. What Stage, the venues main, offered sets from The Avett Brothers, Sharon Jones & The Dap-Kings and Rodrigo Y Gabriela.

The comedy tent offered appearances from Aziz Ansari, Garkfunkel & Oates and Rory Scovel while the cinema tent played an advance screening of “Hit & Run”, hosted by its stars Dax Shephard and Kristen Bell.

Inevitably, however, it was the much-anticipated set from headline act Radiohead that stole the day. Flanked by an enormous (almost interactive) series of moving video screens, the Brit rockers delivered a two hour set to a barely containable crowd, ploughing through tracks old and new (some very new) including classic Karma Police, a veracious track “The Daily Mail,” “House Of Cards” and ending their second encore with “Paranoid Android.”
