Japanese band Mugen in 3 from the 80s

 

Very similar to Asturias, but lacking the electronics and more classical symphonic, Mugen:

Japanese symphonic progressive rock band founded in 1984 and disbanded in 1989.

They made 3 in total all with classical European or painterly references, eg Leonardo, Lady of Shalott, Homage to Gustave Moreau, etc. I know some folks adore this type of music but for me it really leaves me kind of cold, mostly because it's so clearly derived from a mix of classic progmeisters such as Genesis and the old Brits like Renaissance, Gryphon with the baroque importations plus classical chamber stuff, add to that heavy on the strings, but luckily quite a bit of the gorgeously tender mellotron plays...  What disappoints me the most is the chord progressions are so inevitably predictable with none straying beyond the basics, eg A minor / G / F / E7, as an example, circle of fifths type stuff (C, A minor, D minor, G7).

Here and there are some nice listenable moments, for ex. Leonardo from the first album is reminiscent of my old fave Mr. Sirius (whose arrangements and chords are stunningly original in side by side comparison):

Salome from the 2nd album has some very Genesis parts in the middle but not quite as urgently cohesive as their works:

Anyways, you get the idea.  The mellotron that scoots in and out of songs here and there is a joy to hear, as always, and thanks to them for that.
