I saw this video while I was at work a few days ago and I thought it was tremendous and worth sharing.
While Robbie is using it in a modern jazz based context, I could see this making for some incredibly interesting sounds in a more metal or prog context - the note sequences remind me of Tosin Abasi’s selective picking and thumping.
