The Haunted really like you, but they don't wanna ruin things, you know? So the band slowed things down on "Spark" because they just wanna take the time to get to know you really well as a person.
Seriously though, "Spark" is a bit of a slow-burner that's stuffed with destructive, fairly simple riffs, and a totally chant-able chorus that seems like it'll be a staple for the band live.
Strength In Numbers is out August 25, and you can pre-order that here.
