Pet Shop Boys sounded like shit
i guess it depended where you sat, because from my position (fifth or six box, right side) the PSB sounded great. what a great show that was...
the thing with DAR is, as every good lawyer will tell you, "it depends" - depends on PA used, the sound techs (and their familiarity with the venue or similar), the type of music, you position in the hall. when compared to a venue like The Anthem that always sounds good, then yeah DAR sucks because of its inconsistency.
there was a stand-up show i saw there - might have been Eddie Izzard? - had such a terrible slap-back echo that the audience started shouting "we can't hear you!", "fix the sound!", etc. they stopped the show for a minute, some improvements may have been made (i couldn't tell as i was up front where the performance was intelligible) and the show went on with fewer heckles about the sound quality.
