Think of Jukebox the Ghost as the second coming of A-Ha, if the latter had an interest in both postmodern philosophy and all-night dance parties. The Brooklyn trio is an exuberant bunch, a group for whom it makes perfect sense to pair heavy topics with light, syncopated melodies. “We like talking about life and emotion and deeper things,” vocalist and keyboardist Ben Thornewill explains, “but we also want to be doing pop music, music people will enjoy listening to and enjoy dancing to.”

Thornewill says his band’s previous album, Safe Travels, was written in a time of emotional turmoil; topics like mortality and the supernatural are paired with sweeping orchestral arrangements. The band’s most recent self-titled album is more radio-friendly, moving from feel-good anthemic tracks like “Girl” and “Hollywood” to “Undeniable You,” a heartwrenching solo piece that has Thornewill railing with—and against—his own voice, looping his vocals in the live arrangement.

But what makes this power-pop group pop is not its music’s crafted aspect, but its ability to draw inspiration from and riff off its surroundings. Three days into its latest tour, the band had already swapped covers with opening act Twin Forks. With guitarist Tommy Siegel, Thornewill keeps the banter going, always quick with a joke about the latest tour stop. Drummer Jesse Kristin pulls the dynamic together, a perpetual smile on his face as he keeps the beat. In an age of music-on-demand, each performance is a different experience. With Twin Forks (feat. Chris Carrabba), Secret Someones.
