Chemistry

One of the relatively rare Rush songs where all three members share a lyrics credit. The song explores the mysterious, ineffable forces that draw people together — the "chemistry" of human connection that can't be fully explained by logic or reason.

Musically, it's one of the more synth-driven tracks on the album, with layers of keyboard textures creating a dense, atmospheric backdrop. The arrangement reflects the era's fascination with electronic textures while maintaining Rush's signature rhythmic complexity.

While not among the album's most celebrated tracks, it demonstrates the band's ability to write about interpersonal themes in a way that's neither sentimental nor detached — a balance Peart's lyrics increasingly struck during this period.
