Hardcore is underrepresented in videos, but Hardcore Riot just made up for it with an hour long live set. This does a great job of representing the genre. I'm not sure what is running on the iPad, other than the laser show reflecting off the screeen, but one of the guys touches it a few times throughout. I assume it is doing something useful!
Here is a one hour video of one of our livesets, recorded at our studio in Bergen, Norway. Ths set has over 300 different wave/rex2 loops and more than 200 different instrument loops on the Korg Electribe. It turns out completely different every time we play it, and we constantly update it so no 2 livesets will ever sound the same.
Equipment used: Korg Electribe MX-1, Korg Kaosspad MK3, Novation SL Zero MK2, Ableton Live, iPad.
