An explanation: In Summer 2008, at the end of my time in Tanzania and after leaving Tabora, the remote town in western Tanzania where I was volunteering with an NGO focused on ICTs for Development, I went to Arusha, in the northeastern part of the country. My partner was working with an NGO focused on sustainable agriculture, but she had, in the course of her work, befriended a young Maasai chief named Isaya, and was helping consult him on a well-drilling project for which he had raised a tremendous amount of funds by running the London Marathon. Isaya took us up to his village in order to meet his family and so that we might walk through the country where the well was to be drilled. These songs were recorded throughout the course of an afternoon and evening, when many neighbors came to Isaya's boma (a kind of compound, with several huts, a large fence, and an enclosure for livestock) and sang, danced, and otherwise celebrated all night.
I don't know what most of the songs mean, nor do I know their names. Maasai song has a traditional structure, where one man or woman sings the first line of a song, then the others recognize the line and sing the response. Many songs continue on in this manner. The men frequently use throat sounds to create percussive noises, and polyrhythms are frequently used. The first songs especially involved lots of dancing, which in Maasai culture generally means jumping competitions, which are an amazing sight.
