1930s - 1940s
Notably Isaac Mzobe's Crocodile Male Voice Choir recorded a number of tracks (XU 12-14) in 1939.
A later recording by the same group (XU 30) is tentatively dated circa 1941.
Recordings by the Amanzimtoti Male Voice Choir (XU 32, 33, 38, 41, 42) similarly are dated circa 1941 and two tracks by the All Nations Male Voice Choir (XU 63) are dated circa 1942.
Veit Erlmann dates a number of the Better (XU) label recordings from this period in his book Nightsong.
