Synth-heavy production duo The Knocks have teamed up with New York’s own indie rock darlings St. Lucia, which seems like an unlikely collaboration, except both used to be on Heavy Roc‘s label so perhaps that’s where they initially met. The result is “Modern Hearts” and it’s a gleaming bit of indie pop that has enough dance in it to make it you want to hit the floor. The collaboration will be released as a single on April 16 through A&M/Octane Records.
