Call us simple, but the three things we love right now are summer, parties and the amazing electronic disco of Heartbreak. Luckily, all three collide this Sunday when Lex Records hosts its all-star Crush event at Cargo in East London. From 7 PM to midnight they've lined up live action from Gruff Rhys and Boom Bip's Neon Neon outfit, Heartbreak, and Willie Isz (aka Khujo from Goodie Mob and Jneiro Jarel's new hip-hop supergroup making their UK debut), plus DJs from Dissident, Cocadisco and Fluokids. We've got three pairs of tickets to give away to this party. To be in with a chance of winning, answer this question – How many people are in Heartbreak? – and email your answer here.You can buy tickets to Crush here and in Rough Trade East shop.
