With induced resonance you won't just *hear it* you will actually *see it* (the tonearm will appear to be alive, depending on the speed of the warps etc...).
Another observation is that the sound can exhibit "phase-y" behaviour i.e. a centre vocal, instead of being stable and centred, can appear to split into 2 separate voices one in each channel!
(...and, as has been pointed out, things can get even more violent)
