Martin Rott’s “kinetic theory, Pt. II” turns a nighttime bike ride through central Berlin into a study of motion under pressure. The piece comes from the image of his son riding at terrifying speed, with anger becoming energy rather than stopping the movement. That idea extends into the city itself, where the Symphony Hall becomes a reminder that the same forces can find different forms of expression. Movement here is physical, emotional, and musical.
The piece also carries the harsher mood that separates it from “Kinetic Theory (pt.I),” which grew from the desire to move again during lockdown. Pt. II comes from a harder reality, and its rawness keeps the music close to that feeling. Analog electronics provide the motion while the unprocessed string quartet brings another texture into the same forward drive. Neither element needs to dominate. They occupy different parts of the same push.
There is something fitting in the connection between the bike and the music: both keep moving because stopping would leave the accumulated energy with nowhere to go. Berlin passes outside the rider, the Symphony Hall becomes one more point in the route, and the quartet joins the electronic pulse without smoothing it out. “kinetic theory, Pt. II” keeps pressing forward until the movement itself becomes the destination.
