Las 66 Favoritas de Jose María Íñigo y José Ramón Pardo. Vol. 1 (1958-1961) [Remastered]]

Classic soul is the 1960s–early 1970s strain of soul music that fused gospel's emotive vocals and church-derived harmony with the backbeat and instrumentation of rhythm & blues. It emphasizes powerful lead singing, call-and-response with background vocals, tight rhythm sections, and punchy horn arrangements. The sound ranges from uptempo, danceable singles to deeply expressive ballads in 12/8 time. Production is typically warm and analog, with live bands, tambourine and handclaps on the backbeat, and arrangements crafted for immediacy and drama. Lyrical themes center on love, heartbreak, perseverance, community, and, at times, social conscience.

Jazz blues is a hybrid idiom that merges the expressive, melodic language and 12‑bar song forms of the blues with the harmony, improvisational vocabulary, and rhythmic feel of jazz. Typically, it retains a blues structure (often the 12‑bar form) while enriching it with jazz devices such as ii–V progressions, secondary dominants, turnarounds, tritone substitutions, and extended chords (9ths, 11ths, 13ths). The feel commonly swings, with walking bass lines, comping on piano or guitar, blue notes, call‑and‑response phrasing, and solos that mix blues scales with mixolydian and bebop lines. The result ranges from earthy shuffles to urbane, harmonically sophisticated vehicles for improvisation, sitting comfortably between New Orleans roots, Kansas City riff traditions, and modern bop language.

Piano blues is a blues tradition centered on solo piano performance, where the instrument carries both rhythm-section drive and melodic lead. It fuses ragtime’s syncopation, early jazz phrasing, and the 12‑bar blues form into a percussive, highly expressive style. Hallmarks include steady left‑hand patterns (walking tenths, stride figures, broken octaves, and boogie ostinatos) supporting right‑hand riffs built from the blues scale, blue notes, crushed grace notes, tremolos, and call‑and‑response motifs. It flourished in saloons, rent parties, theaters, and recording studios, giving rise to regional approaches like Chicago’s understated, swinging shuffle and New Orleans’ rolling, rhumba‑tinged feel. Closely related to barrelhouse and boogie‑woogie, piano blues underpins much of later American popular music, feeding directly into jump blues, early R&B, rock and roll, and rockabilly.
