Longstanding Chilean band, Congreso Part 1: early LPs [1971 El Congreso, 1975 Terra Insognito, 1977 Congreso, 1978 Misa de los Andes]

 

Information here (from discogs):

Chilean band based on brothers Patricio, Sergio and Fernando González Morales, who in 1964 founded some folk-pop bands as "Los Stereos", "Shadows" and "Los Masters". When Pancho Sazo joined them in 1969, the band finally called themselves "Congreso". Later some chilean important musicians as Joe Vasconcellos or Jaime Vivanco played on the band.

Latest line-up: Sergio Tilo González (composer, drums); Francisco Sazo (lyrics, vocals); Hugo Pirovich (flutes, percussion); Jaime Atenas (soprano & tenor saxophones); Sebastián Almarza (piano, keyboards); Raúl Aliaga (marimba, ethnic & electronic percussion); Jorge Campos (bass, vocals) and Jorge Abarca (sound).

In this instance, wikipedia provides more fleshed out information, starting thusly:

Congreso is a Chilean Latin American fusion band founded in Quilpué in 1969 and led by Sergio "Tilo" González . In their more than 50 years of career, they have released 18 studio albums and 4 live albums, including a DVD. They began their career in the late 1960s, linked to the Nueva Canción Chilena (New Chilean Song) movement . However, with the arrival of the military dictatorship and the cultural restrictions of the time, coupled with the strong instrumental vocation of its members, they evolved towards progressive rock , and then towards a fusion sound that also incorporated elements of jazz fusion , contemporary music , pop , and world music —a sound they called Nueva Música Latinoamericana (New Latin American Music ). This transformed them into a fundamental pillar of Chilean popular music. They have earned national and international recognition from both the public and specialized critics for their refined musical compositions, as well as for their socially conscious lyrics. In its first stage, along with Los Jaivas and Los Blops , it formed one of the essential bands in the new Chilean progressive sound and the Chileanization of Rock.

These early albums are exactly what would have turned me away in a cursory check, being acoustic folk, ethnic-based, with no electricity-- either metaphorical or instrumentally plugged-in.  There are so many similar South American bands, which operate within the same sphere of ethnic folk with very predictable chord progressions and presumably very political lyrics, I'm guessing.  Although I am not sure how the dictatorship of Pinochet connects, since I'm presuming that there was a great deal of suppression of protest and dissidence.

However, in the 1977 ST work, there is a hint of the great compositional works to come in the epic Arcoiris de Hollin, with the very broad symphonic progression and chamber arrangements that provide interest and variety, in addition to considerable dissonance, note in particular how frequently the song completely changes directions like a small bird in ceaseless flight:

And in fact after the 1978 Andean Mass, for some reason the band just explodes into the progressive sphere, no clear reason that I know of, but presumably there is some explanation, and we'll observe that in part 2 coming up.

Incidentally for those who are not familiar with the political history of Chile in the later 20th c. I recommend you review it for its sad horror, with the familiar themes of cruel dictatorship, neverending meddling by that big North American 'democracy,' siphoning off of riches by the oligarchy with enforced austerity for the masses, 'opening up the country' to neoliberal policies = selling off everything in the country to multinational corporations, etc. such as we see now in Argentina still.  (Incidentally, their practice then of 'banning all leftist parties and doctrines' might be quite premonitory for us here in the 'West'.)

When I read these histories I feel truly sad about humanity, thinking it's our natural state to be ruled by all-powerful autocrats or autocracies.  Especially when I think back to how much hope for the future of the world we all still had in our youth, back for ex. in the late 1980s, 1990s.   All evaporated.

Then if I go for a walk in the shopping mall and look around at the folks there it occurs to me that these people couldn't care less if their government was a dictatorship...
