Ramon Farran - El Corto Vuelo Del Gallo from 1980 Spain

Here's a totally unknown one.  Discogs bio:

Spanish jazz drummer, composer and conductor, born in Barcelona in 1939. Son of R. F. Tutusaus, he started very young playing drums in his father's big band, "Orquesta Plantación". His career was oriented to jazz-fussion, and he played with Sonny Rollins, Don Byas, Chet Baker or Joe Henderson. He was producer in the 60's (Juan y Júnior) and composed for Julio Iglesias. He composed also the soundtrack for TV series "Los marginados". He wrote the soundtrack for "Ilegally yours", by Peter Bogdanovich. Founder in 1999 of Orquesta Nacional De Jazz De España (ONJAZZ), officially known as "Fundación Orquesta Nacional de Jazz de España" (FONJAZZ).

The first track introduces the theme with its characteristic circle of fifths Italian seventies soundtrack like sound, which is repeated so many times through the entire record albeit in different variations that I daresay by the end you will probably be tired of it:

It appears this is a soundtrack too, all instrumental, with some folk and some acoustic elements, a wide variety of different approaches and sounds, but in the end not quite as prog as I would have liked, despite the description which as always shows an aptness to be misleading, unlike on this blog where we are brutally honest.
