12 July, 2013: Sunny Portugal ain't so sunny for day one of Optimus Alive, but the rolling mist from the sea didn't stop Scottish rockers Biffy Clyro performing a now-trademark shirtless show on the Atlantic coast.

Performing an early set, Biffy were nothing short of spectacular, performing a show that leant heavily on tracks from their 2013 double album, Opposites. The band threw in a number of Biffy classics, with 'Many Of Horror' still sounding spectacular, despite the Matt Cardle mauling in 2010.

Check out photos of Biffy Clyro live at Optimus Alive, right here - and check back for shots of Green Day, AlunaGeorge, Green Day and many more as we party on into the night...
