Chipmunk Rock features The Chipmunks covering various rock hits, mostly from the late 70's and early 80's. The album is currently not available on CD.
Chipmunk Rock starts off with The Chipmunks practicing the song "Down by the Old Mill Stream" for a performance at the local PTA. Dave then departs and warns "none of that rock and roll business." The boys sing the various rock hits when he's gone and finally resume singing "Down by the Old Mill Stream" just in time for Dave to walk in.

- The album name and cover is a parody of Deep Purple's In Rock.
- The trio name-check the not-yet-created Chipettes in the song "Leader of the Pack," when Alvin complains at the idea of singing "a girl's song!" Theodore then jokes "So? You've never heard of The Chipettes?" Two years later, The Chipettes would make their debut on the 1984 album Songs from Our TV Shows.
