Song of Frogs in Malaysia won sound beauty contest

I wonder what these swamp rappers communicate... it seems to me fairly complex.
Frog symphony Scroll down to the middle where there is a Soundcloud version.

This reminds me of a Herbie Hancock cool jazz tune I listened in the late seventies on vinyl... The "jungle sounds at the beginning and at the end really put me in trance each time I was sipping my morning hot chocolate in the project housing, ready to cross the drab factory district to get to the high school downtown.

Wow! I listened to both the jazz piece and the live nature
recording of frogs singing in Borneo all the way through,
which is something I rarely do with anything musical these
days. (Except the Hindu mantras I use in magical workings,
which I see as being in a category of their own.)
