Fantasia Cromatica's one-off

 

An excellent review that starts like this:

With a name taken from both Bach's chamber tradition and Jaco Pastorius' repertoire, Argentinean ensemble Fantasía Cromática brings a refreshing stance for contemporary jazz-rock. The band shows clear, undeniable evidence of the influences absorbed from Pastorius-era Weather Report, Return to Forever, Yellow Jackets and Brand-X, with some soft hints to symphonic rock in places. The album kicks off with the vigorous 'El Proceso de la Lluvia', which sets a proper mood of joie de vivre in the listener's mind. The track is set on a controlled basis, obvious in the harmonic fashion in which the guitar, sax and synth solos succeed each other; he middle section is much slower, which gives way to vocative ambiences (including a very Gilmour-esque guitar solo). 'Un Gesto Memorioso' begins with on a reflective tone with the sax assuming the starring role - once things shift to a more intrepid mood, the guitar and the bass display a mutually defiant homage to Holdsworth and Berlin in a tasteful use of pyrotechnics. 'Ascesis del Sol' is the longest and most solemn track in the album: this makes sense with the important presence that the keyboard layers bear during the elaboration of the track's main atmospheres: the sax and piano solos are relevant, but again, this band likes to keep things under control, so the potential storm of virtuosity is always obedient to some sort of constraint, always giving major preference to the global sound. The bass ornaments featured in some passages also help to sustain the overall mood...

You can tell from its posting here that we're dealing with a throwback to the seventies greats, so much so that there really is no indication this wasn't recorded back in that glorious heyday of progressive fusion. 

The so-called solemn track with its highly evocative transcendent (and original!) chord changes, Ascesis del Sol:

Oddly I don't find a database entry in discogs to see if there's more from them.
