Conexion's Harmony, Spain 1973

 

From Discogs, as usual:

Conexion was a kind of Spanish version of Blood, Sweat & Tears and Chicago, i.e. up-beat, song-oriented jazz-rock with brass and guitars. Their first album had a side-long track of greater interest, an ambitious instrumental named "Concierto Uno".

It's also similar, particularly in the harsh baritone vocalizing, to the early 70s Dr. Music I posted here before.  Our Music gives you an idea:

Of course, given the above, pay attention to the sidelong concerto, it's quite good though perhaps not 'quite good' in the sense of Valentyne Suite or the Grand Canyon (Suite) by Patrick Moraz, or from this blog, the much rarer but masterpieceial Garuda Suite.

It's too bad they didn't put out more music like this.

Metarythmes de L' air - Phagocyte 1984, requested

Beginning in the highly literarily overrated year of 1984, they made a few albums and this is their first.  I've posted a great deal of this style of jazz-based RIO, which was popular especially in Germany but also among jazz musicians in France.  Some of it is clearly improvised, and therefore rather meandering, but some of it is well worth hearing for its unique sounds, melodies, chords.  

The first track as a sample, called Vertige (dizziness):

Flux, 1973 UK

From discogs:

Short-lived art rock/fusion band comprised of ex-Motiffe and ex-Babe Ruth members. They were offered recording contracts but split up and went in different musical directions. Grimaldi went on to Argent directly after Flux, and helped craft their forgotten masterpiece Argent - Circus, while another member went to Flea On The Honey.

This is well worth hearing, featuring some genuine progressive material here and there.  There is definitely a lot of variety to the tracks, with some ranging from all out crazy to others just ordinary.  My biggest complaint actually would be the recording sound which is a bit subpar.

The song called Atonal is not that, unfortunately:

Plesni orkestar RTV Ljubljana – Križanke (1976)

 

Information on this interesting release can be found here.  Note that these guys made a ton of stuff in the period in question but it seems mostly covering standards I think.  And also you can observe that the wonderful trumpeter Petar Ugrin posted earlier plays here.

The driving energy on the track called Krizanke '73 is beautiful:

B P Convention Big Band, 3 albums

Mentioned by a commenter, they made 3 LPs back in the seventies as you can see here.

It's very much in the old big band tradition from earlier however with very little fusion.

Members:
Albert Mangelsdorff, Art Farmer, Boško Petrović, Clark Terry, Damir Dičić, Ernie Wilkins, Gianni Basso, Karlo Takač, Ladislav Fidri, Marcel Fuchs, Marijan Domić, Mario Mavrin, Ozren Depolo, Salih Sadiković, Zlatko Dvoržak

Note that the middle album, with vocals from Josipa Lisac, is basically rock or pop standards (Yesterday, Didn't We, Something, Sunshine of My Love, etc.)
