(Yes Blockx with an x at the end not a typo!)
1851-1912 Belgian composer, a leader of the Flemish nationalist school in music. He composed mainly opera but also a few chamber/orchestral works.
His Triptyque Symphonique 1893 has three movements: 1. Jour des morts 2. Noël 3. Pâques
I have completed a working of the 3rd movement Pâques. It's something very different to my ears. I hope you enjoy it.

The RCM has a volume of his piano music and songs (34 in total), at least some of which appear to be unique to that Library: https://rcm.koha-ptfs.co.uk/cgi-bin/koha/opac-search.pl?idx=&q=D3152*+Blockx (https://rcm.koha-ptfs.co.uk/cgi-bin/koha/opac-search.pl?idx=&q=D3152*+Blockx). Images of at least the first pages of music are included in the catalogue records.
His name has certainly fascinated me for some time since he appears to have had a lot of music published - including substantial works like operas and symphonies - yet is practically unheard of today. And only one recorded work available on Naxos.
Yes, you rarely come across his music. I just have his very enjoyable Five Flemish Dances on a Marco Polo disc and his Flemish Fair (from Milenka) on a Discover CD (https://www.amazon.com/Salve-Antverpia-Romantic-Symphonic-Antwerp/dp/B00000220E (https://www.amazon.com/Salve-Antverpia-Romantic-Symphonic-Antwerp/dp/B00000220E)).
Lots of interesting information about him and his operatic works at: http://www.401nederlandseoperas.nl/en/component/content/article/311-jan-blockx.html (http://www.401nederlandseoperas.nl/en/component/content/article/311-jan-blockx.html)
