What is the fine-grained topic of the following text: Since I became so interested in Gnawa, Iit would shave been nice to have a longer lecture on the history of Gnawa and the structure of the music and if the musicians had played longer and explained what they were playing so I could have learned more about what words they were singing, the purpose of the song, where it is sung, the response on people and the role of the trance in the religion and more about the symbolism of the clothes. Only return the topic.
Desire for deeper understanding of Gnawa music and its cultural significance
