' full-length debut, , packaged the seductive, tandem lead vocals of and in a musical array that spanned earthy folk textures and dramatic, '80s-glossed dance-pop. Their follow-up, , springboards off of the latter and lands with a slick and boisterous design colored by '80s pop production to a degree that it may cause occasional flashbacks to anything from high-tension to the brightest of . The vast majority of the time, though, the album keeps all attention in the moment as the two songbirds belt, flit, and croon their way through a bold song list. Co-produced by the band and ( , ), the record eases listeners in with the soft, a cappella opening of the wistful power ballad "Madness." Gentle strings and spare drums join the women's harmonies, before both droning and prodding synth timbres conspire with the vocalists for a full-contrast, attacking chorus. Similarly, "Gone Insane" thematically and almost literally goes from a whisper to a scream, with the singers actually losing their vocal composure at one point in the song. Possessing more level dynamics, the early -inspired "Almost Makes Me Wish for Rain" is still full of spunk and supple performances. has the overall effect of being very loud, even if in reality offer athletic variations in delivery and there are quieter moments to be found in the record's mix. With attention to song intros and outros, the song sequencing provides necessary balance between ballads and boomers. "Something About You," a diva vehicle with rumbling synthesized tones, for instance, is followed by the tenderer if still powerful "What We Have (To Change)."
