Julius Engelbert Röntgen (1855-1932) – Chamber Music

[britishcomposer]

John and Alan, I have a recording of a concert broadcast of the Pno Quintet op.100. Would you like me to upload it?

I have digitised my recording of Röntgen's String Quartet in F sharp minor (1927). This was a Dutch Radio 4 broadcast from the 1990s.
I don't remember the exact year but the announcer said it was first performed on March 15th of that year.
The performers were the members of the Matanyi Quartet who have also recorded other Röntgen quartets.
Can anyone help me to find out the year of this performance/broadcast?
Has anyone perhaps a better recording of this broadcast or knows of another recording/performance?
Otherwise I would offer to upload my own.
