"Rocket Queen" closes side one of Appetite for Destruction with the album's most structurally adventurous composition. The song begins as a hard-driving rocker at approximately 114 BPM in F, featuring Slash's first guitar solo, a gritty, mid-tempo statement full of expressive bends and aggressive phrasing. Midway through its six-and-a-half minutes, the track undergoes a dramatic transformation, shifting to a slower, more melodic section in E-flat at about 111 BPM where Slash delivers a second, more lyrical solo over a warm, almost gospel-tinged chord progression. This two-part structure makes Rocket Queen unique on the album, functioning almost as two separate songs joined by a musical bridge. The first half channels the raw sexuality and aggression that characterizes Appetite for Destruction, while the second half reveals a tenderness and emotional vulnerability that provides a striking contrast. Rose has stated that the song was written for a friend, with the gentler second section representing a message of support and encouragement. The rhythm section's performance is exceptional throughout, with Adler and McKagan seamlessly navigating the dramatic shift in mood and tempo. Rocket Queen is widely regarded by fans and critics as one of the finest tracks on an album full of remarkable performances.
