I feel like with this music it's hard to separate the dance, song, and religious context. Have you experienced trance states in the sense that practioners do with Orishas embodying participants, or do you mean something else by "trance?"

I think it's also interesting you indicate listeners, rather than the drummers getting into that state - my memories of learning bata drumming are largely of going into a hyper-focused state that I wouldn't describe as trancelike, but also very different than the mindset I was in playing something like orchestral music.
