Good sounds to time-stretch?

Ideas & suggestions
1

Just looking for a quick list of good sounds to time-stretch in CDP. I found that metallic sounds give good results. Any other suggestions?

It seems that Aphex Twin tracks are still beautiful when stretched from 10 to even 1000 times slower !!!

There are some examples on YouTube.

So let’s say that some electronic sounds can do the job!

I heared good stuff based on AFX analog waves, prepared piano, distored bass…

Prepared piano might be cool, I got an old out of tune one here in my house. Gonna bang out some noises on it now, and see how they work out.
