Reversing stereo channels or turning around can replicate hearing music from behind the orchestra

Evidence

It is interesting to compare the normal concert hall layout as a listener with the experience of sitting in the audience area behind the orchestra, which is possible in halls such as the Royal Festival Hall in London. Unfortunately, this is not a test that can be carried out very satisfactorily, since it is not usually possible to sit far enough behind the players to gain as good an overall balance as can be obtained from the auditorium in front of the orchestra. It is, however, possible to experience this effect by turning round when listening to a good stereo recording over loudspeakers or by reversing the left and right channels. β€” David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1638
