African music really began to boom in the 1950's. Africa's economy had been doing well and new musical styles were being developed. Two new orchestras had been formed along with vocalists and dancers. By 1966, each orchestra was well known from many songs and dances. Their dances contained a variety of movement ranging from a lot of time periods. Animation became a well known theme during this time too which is where there are instructions directed to the crowd of how to dance and the crowd then follows the steps. However, in the late 1950's things were not so great. Dictators took over the Congos which is where many talented musicians lived. The people migrated to other African countries, the US, and to Europe. The style of orchestras and dance then spread around the world. As the 1970's and the 1980's went on, African music just kept spreading. The music became much more diverse with different instruments and ideas.

After all of these new ideas had been developed, the music in the 1980's was full of talent. There were many performances all over Africa with every possible instrument you could think. The music had been spread so far around Africa that different music and dance had been combined together and used for a wonderful look and sound.
