online resources for extended techniques?

I came across this great site for flute extended techniques recently,it's one of the best I've seen because for each technique it has sound samples and describes the notation. Does anyone know of any sites for other instruments? Especially with sound samples? I know the Jay C. Easton page for woodwind extended techniques, but it doesn't reallly go as in depth as the Mats Möller one with sound samples

Each instrument has a set of demontrations.. for normal use, and extended techniques (see "extended" on the left for each instrument) Many videos, and some notational examples.

Not a lot of depth, but some concepts are there.

thanks, this is great!

I am extremely interested in the site you all mentioned but i cannot open them. I live in the Netherlands. Can anyone help me?
