This is one of the brightest prog pearls from Poland. Exodus come from the '70s - when it wasn't so easy to be a rock band in their country - and released their debut album in 1980, including this title track. "Ten najpiękniejszy dzień" (meaning "The Most Beautiful Day"). It reveals a strong symphonic side, but even if there are some definite Yes references, I daresay this is an original way to prog. The suite is set up following classical structures and the themes are all very good.
This album also includes three shorter and pleasant tracks.
There's a strong rythmic, dynamic background, but I also like the atmospheric interludes, something between prog and space rock. The track is divided into four movements, some of them featuring interesting vocal harmonies, that remind me now and then of traditional Eastern European ensembles. Most of the interplays are great, involving all the instruments in turn and sometimes leading to bombastic walls of sound. That said, there's no useless pomp in this song, just the good deal of sense of wonder we all like in a prog suite. Highly, highly recommended.
