Tribal is a kind of music that i am currently addicted to. It has hard bass but not a simple boom boom boom boom four beat.

When you hear tribal music you can just see a jungle with a naked man pounding away on a set of animal skin drums with sticks. In the background a herd of zebra run by and this dude is just going to town. The rest of the tribe is dancing around and singing. They are al wearing big masks and are holding spears. There is a big fire in the middle. Its intense.

Ok back to reality if you haven't heard tribal music give it a try it great stuff.
