Its the artists and their clothing, or that's the trigger
only percussionist and the trombone players have to move as much as someone playing a bowed instrument.
What makes the sound strange is the gating and compression used in the recording to help reduce extraneous noises from creeping back onto the mics which could carry over onto oncoming parts of the performance and be even more distracting. Just shifting in the chair makes some noise that a mic will pick up. So gating is used and that's mostly what your're hearing.
At school we used to watch quartets in a church and the lite attendance for Friday evening concerts allowed us to sit right up front and the players clothing (especially men in tux/suits often made extra noise as did moving in their chairs.
All things you don't want on a recording.
