This group of musicians recorded at least fourteen individual songs or instrumentals for the Victor company as the "Srpski Muški Kvintet" between May and August of 1917. Unfortunately, it seems that only eight recordings were ever released. I've posted four of these tracks below.
The first record is a great instrumental medley of Serbian and Croatian songs and dances (side A is mostly songs, and side B is mostly dances). The second record starts with an upbeat old patriotic tune, "Napred Stupaj", also known as "Srbijanci i Bosanci", or "Kralja Petra Pesma". The flip side is a nice rendition of the popular old song "Oj devojko! Oj!", better known as "Ti si rajski cvet", featuring lead vocals by Ćira Kozarov.
