An entirelly percussive piece

I have this idea for some time now, to do a piece something like a cine-que that will be performed only with orchestral percussion and maybe some exotic instruments. I have already done a kind of a demo, so I don't forget it and it lasts for about 3:30.

Now the thing I am not sure about is, will it be boring after some time, I have much development in rhythms and change them a lot, but I get into temptation to throw in some strings and maybe some vocal work like chant and something... its supposed to sound very primal and tribal like.

So what do you guys think?

there are tons of things written for percussion ensembles. I'd say go for it. Search Youtube for percussion ensembles and see what you get.

Listen to "Ionisation" by Edgard Varese, and "Ku-Ka-Ilimoku" by Christopher Rouse. You just might be amazed. :)
