UvA listening experiment

hello everyone!

the university of Amsterdam is having a series of listening experiments about time-stretching techniques and you're asked to tell which of the two recordings is the original. The site itself explains how it works and can be found here; http://cf.hum.uva.nl/mmm/drafts/2nd-index.html Afterwards you will recieve an email with the correct answers and who the composers of the music were.

Anyone care to contribute their experience or dare to take a chance?
