Two days without washing! Pizza and beer! Brightly coloured T-shirts everywhere! Hack Day is a festival by any other name. And all good festivals need music! So on Sunday night, after the hacking is done, Hack Day is proud to present The Rumble Strips in concert.
And because we know that going to a concert by yourself isn't that much fun, you can invite some friends to come along as well... Add the names of (up to) three of your friends in the fields below, and they'll be able to join you inside Alexandra Palace from 7pm on Sunday night.
You have to be a logged member of the site to request guest invites for the hackday party.
