Music of pearl divers

One friend on the internet informed me about Fijiri music. This is music, which is mostly vocal and It is played in eastern arabic gulf states, mainly in Bahrain and Kuwait. Singers imitates such things, like taking boat to the water, swimming on the gulf and, there are also percussions too to accompany singers. They sometimes sing to god for help. One of my friends says, that this music is very similar to something, like It exists in Sufism.

Here is preview of this music. You can listen and maybe, You are from this region, so You know very well this music.
