Here are some videos for perusal...
Taken from a live stream concert of the Unerhörte Musik series from May of 2020 from the BKA in Berlin.
Berlin PianoPercussion concert in Konzerthaus Berlin: Sawami Kiyoshi and I playing Eutropia by Andre Bartetzki in January of 2020. It is one of the few pieces where the video reacts to the sound. My favorite part is 1:22 - 3:20.
And one of my all time favorites, Zyklus by Stockhausen
Check out the middle of the next one for some adaroll technique, one handed marimba roll.
And why not, one of my favorite pieces, Weiss / Weisslich 31e by Peter Ablinger
And naturally Tom Johnson's Nine Bells
As well as the start of Nine Bells
