Abstract
I argue that the work of art in rock music is a track constructed in the studio, that tracks usually manifest songs, which can be performed live, and that a cover version is a track (successfully) intended to manifest the same song as some other track. This ontology reflects the way informed audiences talk about rock. It recognizes not only the centrality of recorded tracks to the tradition, as discussed by Theodore Gracyk, but also the value accorded to live performance skills, emphasized by Stephen Davies.
