"Fanfarecorps te Sipirok in de Bataklanden" A Toba Batak brass band from Sipirok, Tapanuli, North Sumatra, Dutch East Indies circa 1890. I had no idea there were Western style orchestras there so early.
(Saw low-res versions of this making the round in historical Indonesia fb groups and found the original on KITLV via a reverse image search and a citation in a textbook where it was reprinted.) #Indonesia#Sumatra#Batak#BrassBand#MusicHistory
