His sets are characterized by their intensity and dynamism, giving the audience no respite, where it's not uncommon to hear tracks of hardcore and xtreme schranz. Schranzchez enjoys experimenting with faders and effects, and it's common to see him performing sessions with three decks simultaneously.
