I can only imagine how difficult it must be to balance a mix between a live orchestra and a movie soundtrack, but there were noticeable audio problems with that mix while watching Batman In Concert at NJPAC on 3/2/2024. Note: I am a semi-professional sound mixing engineer; but my generic comments would probably be said by anyone attending that night.
Don't get me wrong, I really enjoyed listening to the NJ Symphony Orchestra's well-rehearsed and conducted performance of Danny Elfman's original score from the 1989 movie, but the sound engineers should have brought up the dialog levels, especially in quiet scenes where the orchestra's level completely overwhelmed the dialog. If it weren't for the English subtitles on screen, I wouldn't have been able to follow the story.
And this might be Warner Bros fault, but many of the sound effects and foley were missing entirely from the recorded soundtrack. It was like listening to the movie during its Post-production dubbing stage when not all of the sound effects and foley are available yet.
And why on Earth did they replace the Joker's canned laughter effect after his fall from the church tower? As annoying as the original repeating laughter effect was, that was kind of the Joker having his last laugh on the audience even after his demise. It was actually disruptive to the experience by replacing that original laugh track. Did Warner think that fans wouldn't notice? Put the original, annoying laugh track back in, please!
Overall, it was still an enjoyable experience. Nothing beats having a live orchestra play the original score while watching a movie you love. It makes it more immersive and connects audiences more emotionally to the story and characters.
