I agree, it's a he'll of a lot of effort to go to make one of these up and make it look so legit. There are a few off placements as already mentioned (Maggie Rogers, Wunderhorse) but Chase and Status seems far too big to be playing Truck unless they are on a lot of their festivals like YNoT, Boardmasters and Victorious like Jamie T last year.
I've also head Tramlines have got Kasabian and Pulp (via thread , I'm not itk) so maybe we've underestimated the new pulling power of these festivals and in particular, the size of the headliners?
ignoring the top seven, which is believable.
That undercard must be the biggest Truck has ever had by a mile, that’s what makes me question it. If real, I will be well happy.
When was the last time a Truck poster had the lower part populated by Ally Pally & Brixton Academy acts?
