"Hardwood Floor" is a track from The Doors' 1972 album Full Circle, recorded after the death of lead vocalist Jim Morrison. In this post-Morrison era, the surviving trio of Ray Manzarek, Robby Krieger, and John Densmore explored a broader range of musical styles, incorporating blues, funk, and jazz elements more freely than they had in their earlier work. On this particular track, guitarist Robby Krieger takes up the harmonica for a brief but expressive solo passage. Known primarily for his inventive and often flamenco-influenced guitar work, Krieger's turn on harmonica reveals another facet of his musicianship. The solo, played over a rock feel in the key of C at a tempo of 133 beats per minute, adds a raw, bluesy texture to the arrangement. Krieger's harmonica work, while compact at roughly twelve seconds, injects an earthy quality that connects the track to the American blues tradition that had always informed The Doors' music. Full Circle represents a fascinating if commercially underperforming experiment in which the remaining band members attempted to reinvent their sound without Morrison's commanding vocal presence, relying instead on shared vocals and extended instrumental passages to carry the musical narrative forward.
