Spawned out of a hatred for conventional singles nights, Slagbox ditches the awkward table-hopping routine and instead encourages you to write notes to a potential paramour (anonymously or not) which are placed in the slagbox and read out by the comperes. Even if you don't find the love of your life, you'll still have a hot Halloween trot thanks to the very excellent Zara Truss Giles (seriously, listen to her Soundcloud) playing some sexual haunted house plus a live show from meme-friendly synth-poppers Das Kitten. Be sure to dress up and bring an available member of the opposite sex along with you.
