Rock andaluz (Andalusian rock) is a Spanish fusion of progressive and psychedelic rock with flamenco and Andalusian folk traditions. It combines electric guitars, bass, and drums with flamenco guitar, palmas (handclaps), and cante jondo–inspired vocals, often within expansive, symphonic arrangements. Characteristically, it draws on Phrygian and Phrygian-dominant modes, the Andalusian cadence (i–♭VII–♭VI–V), and flamenco compás patterns (e.g., bulería, tangos, rumba), while embracing the timbres and structures of 1970s prog (Hammond organ, Mellotron, Moog, long instrumental passages). Lyrically, it reflects Andalusian identity, poetic imagery, and the social winds of Spain’s late-Franco and Transition eras.

Jazz fusion (often simply called "fusion") blends the improvisational language and harmonic richness of jazz with the amplified instruments, grooves, and song forms of rock, funk, and R&B. It typically features electric guitars, electric bass or fretless bass, Rhodes electric piano, clavinet, analog and digital synthesizers, and a drum kit playing backbeat- and syncopation-heavy patterns. Hallmarks include extended chords and modal harmony, complex and shifting meters, brisk unison lines, virtuosic improvisation, and a production aesthetic that embraces effects processing and studio craft. The style ranges from fiery, aggressive workouts to polished, atmospheric textures, often within the same piece. Emerging in the late 1960s and flourishing through the 1970s, jazz fusion became a bridge between jazz audiences and rock/funk listeners, shaping later styles such as jazz-funk, smooth jazz, nu jazz, and parts of progressive and technical rock/metal.

Progressive rock is a rock subgenre that expands the genre’s formal, harmonic, and conceptual boundaries. It favors long-form compositions, intricate arrangements, and virtuosic musicianship, often drawing on Western classical, jazz, folk, and psychedelic idioms. Typical hallmarks include multi-part suites, shifting time signatures, extended instrumental passages, recurring motifs, and concept albums that present unified themes or narratives. The sound palette commonly features electric guitar, bass, and drums alongside an array of keyboards (Hammond organ, Mellotron, Moog/ARP synthesizers, piano), woodwinds or brass, and occasional orchestral additions. Lyrics often explore science fiction, mythology, philosophy, social commentary, and introspective themes.
