Popshack Live

YouTube channel Popshack gets IRL with this concert of reality TV and viral pop singers. From 'The X Factor'/'Britain's Got Talent' come Union J, Luke Friend, Kingsland Road and Loveable Rogues; from the internet come Jasmine Thompson, Ebony Day and more teenage stars with millions of subscribers and virtually no offline profile. There will, it's fair to say, be some screaming.
