Ultra Music brings some serious dancefloor talent together on ‘I Know What You Did Last Night’. Yk Koi and Lorenzo Cosi a.k.a Sondr come off the back of ‘Kids’, their big track with slap house specialists VIZE, to team up with in-demand producer, Love Harder a.k.a. Will Simms, himself fresh off a recent collaboration with Embody. Both artists are no stranger to success; as individual songrwriters and producers, Sondr worked with Lana Del Rey, Meghan Trainor and Ella Eyre before coming together as a duo. They raced past 100 million streams and show no signs of slowing. Will Simms also has pedigree, working with Aloe Blacc, Lady Leshurr and Cliq before launching Love Harder to showcase his love of dance music – also crashing through the 100 million streams barrier. No surprise then that ‘I Know What You Did Last Night’ ticks all the boxes for a massive crossover tune right in time for Halloween!
