Thanks Phil for some confirmation.
I emailed the venue in New Haven at the time, but never got a reply. I forwarded the email to Lake Street Dive’s management on their website. Didn’t get a reply to that either. I wondered if the artists are aware of this. Maybe they approve. Maybe they don’t know.
At the time I read some reviews of the show on the venue’s website. Mostly glowing reviews. No negatives about the sound.
Somewhat related..I remember some years ago being at a symphony concert at Avery Fisher Hall in NYC which didn’t sound great. I felt lucky that I worked in music studios being able to hear great players through great gear.
