The Libertines filled the "secret" slot on the Pyramid Stage at Glastonbury 2015. It was kept completely under wraps, with gaffer tape over the band name on the flight cases! The first anyone knew of who was playing was when the band walked on stage. This Roadie Postcard from Justin Grealy shows us a bit of what goes on in roadie-world just before they go on stage, and includes a peek at the Alabama Shakes video wall being constructed as well as Motorhead's monitor board - a Yamaha PM5D.
