Brazilian prog-fusion band Quantum, I and II, 1983 and 1994

Some really superb, consistently amazing music from this band featured today.

from discogs:

A Brazilian band formed at the beginning of the 80s, Quantum remained together for two years only. Anyway, it was long enough for them to release their namesake debut album in 1983, which sold more than 6,000 copies. Their style was clearly influenced by Camel and Hackett-era Genesis with added elements of jazzy nature, which provided some peculiar swing to the overall symphonic sound. The 1993 CD re-released edition included a bonus track recorded before their break-up with a different bass player. This bonus track, "Presságio", was actually part of the repertoire of a second album that would never get to be released. Or so it seems, since rumor has it that an actual Quantum second album from that era has been briefly circulating among collectors and fans in cassette format. But a definitely real second Quantum offering went to see the light of day in 1994, when the group reformed and recorded "Quantum II". The new line-up included two keyboardists and no guitarist.

Perfect music for me with just a rich neverending flow of creative ideas that seem to never cease from beginning to end, all in that classic symphonic progressive sound with chamber classical mixed in.  For example, their stunning Sonata:

And if it can be believed the follow up album more than a decade later is just as good, the Sword:
