In a Cuban State of Mind: Silvio Rodriguez's LP "Dias y Flores"... this is i believe the original Cuban LP (blue label) from 1975 on state-run recording label Egrem.. Catalog number LD 3467. Silvio Rodriguez is the most famous exponent of the "nueva trova" ("new troubador") movement which is to my ears a return to folk music (wikipedia sums it up as combining folk music with politicized lyrics..)... pablo milanes is another big name in nueva trova..
