Sleeping With Sirens emerged from the Florida underground with a potent blend of post-hardcore aggression and accessible pop melodies. Buoyed by frontman Kellin Quinn's distinctive vocal acrobatics, the group first commanded attention on their 2010 debut, With Ears to See and Eyes to Hear. The following year's Let's Cheers to This further increased their appeal, but it was the success of 2013's Feel that cemented the quintet's place in rock's big league.
