Step-by-step explanation:
Today's Concept Album can be seen as a modern depiction of the Romantic-era compositional device known as the Song Cycle. The Song Cycle was a group of songs designed to be performed in a sequence as a single entity, often telling a story or exploring a particular theme. Romantic composers such as Schubert and Schumann embraced this form. Similarly, a Concept Album explores a theme, tells a story, or expresses a cohesive mood across all its tracks, embodying the spirit of the Song Cycle in a contemporary format.
