A video sample: https://www.youtube.com/watch?v=zyaFKnUumAM. I find myself quite liking the sound of it, in particular the poem which is recited — the writers of the Shijing (from which the poem is taken) paid a lot of attention to rhyme and assonance. Even so, Old Chinese phonology is really weird: pharyngealisation is decidedly odd even for Sino–Tibetan (though some Qiangic language have pharyngealised vowels), and labialised glottals are only slightly less so.
