Herbert Pirker plays drums lightly to acheive an airy, but dark feel on the drum set. His playing matches the mood of the music. When given the chance at 4:45 in the video below, Pirker plays freely over a vamp set up by the other members of this progressive jazz trio. It's amazing how well the sounds of the instruments blend. In particular, the selection of cymbals really defines the feel of the grooves. They also allow Pirker to utilize non-traditional phrases in the music and during the vamp.
