I can only guess about the origins and status of the National Service Band from Tanzania. I suspect that they were related in some way to the army, but there is no basis for the suspicion. Google only offers an article about Kassim Saidi Mapili, who claims to have been a member of this band (when?).
Listening to the music, there is an elementary influence of Congolese music, but the style has developed into a very original Tanzanian sound. The lead and rhythm (do listen to the rhythm guitar!) guitars are very pronounced and rip through most of the songs. Saxes -but no trumpet-, with traces of Verckys/Musekiwa.
I would guess that the music is from the early 1970s.
If there is anyone who can provide additional information about this (in my opinion) great orchestra, please comment on this post!
