Born To Be Wild (Best Of....)

Proto-metal is the late-1960s hard, heavy strain of rock that crystallized the sonic vocabulary later codified as heavy metal. It bridges blues-rock, garage rock, and psychedelic rock with louder amplification, thicker distortion, and riff‑centric songwriting. Musically, proto-metal emphasizes power-trio or organ/guitar lineups, pentatonic/blues-derived riffs, power chords, and aggressive, often fuzz-saturated tones. Vocals can range from soulful shouts to theatrical wails, and rhythms often push straight 4/4 grooves at mid-to-up tempo with a palpable sense of weight and drive. Historically, it includes bands whose heaviest work predated metal as a named genre, as well as early albums by future metal standard-bearers. Its sound laid the groundwork for the timbre, riff language, and attitude of heavy metal and, by extension, numerous metal subgenres.

Blues rock is a guitar-driven style that fuses the raw feeling and 12‑bar structures of the blues with the power, volume, and rhythmic punch of rock. It emphasizes riff-based songs, pentatonic and blues-scale soloing, call‑and‑response between voice and guitar, and an expressive, often gritty vocal delivery. Typical ensembles are power trios (guitar, bass, drums) or quartet formats adding second guitar, keyboards, or harmonica, and performances commonly feature extended improvisation. Sonically, it favors overdriven tube-amp tones, sustained bends, vibrato, and dynamic contrasts, moving from shuffles and boogies to straight‑eighth rock grooves.
