Radiohead at The Daydream Festival
The pressure was on last night in Barcelona as one of the world's biggest bands took to the stage for their only gig in Spain on their European summer tour. 
If last night was a taster of eco-friendly lighting, the future looks amazingly bright and colorful for the entertainment industry. Radiohead are pushing ahead on the sustainability of all aspects of touring, from traveling less to persuading the crowd drink from reusable cups. Take a look at Petz Scholtus' article over at TreeHugger to find out more about the band's "Carbon Neutral World Tour."
