Rainbow emerged in 1975 from the ashes of Deep Purple, bringing a blend of medieval imagery, complex song structures, and virtuosic guitar work. Those elements aligned with the already‑emerging progressive rock aesthetic, but the band’s commercial success also created a new reference point for younger musicians seeking both technical depth and wider appeal.
The band’s early albums—*Ritchie Blackmore’s Rainbow* (1975) and *Rising* (1976)—demonstrated a hybrid of classical‑inspired keyboard textures and lyrical narratives that resonated with progressive pioneers like Genesis and King Crimson. By mapping these sonic signatures, we can trace a pattern of influence that extends beyond surface‑level genre labels.
