Wikipedia:Articles for deletion/Aleksander Glondys
I find  too arcane to figure out if he has the required albums or such. But pl wiki references his bio with  https://mi.pl/pl/p/Radoslaw-Rabianski-Krakowska-scena-muzyczna.-Encyklopedia/56 this book, which calls itself, roughly, an Encyclopedia of Music in Krakow, and is published by a publishing house https://mi.pl/formy-platnosci affiliated with the reliable Jagiellonian University. So it meets my test for 'a topic that has an article in another encyclopedia'. Well, I am AGF that the subject is covered in this offline source in more than just a passing sentence or two
