I recorded Oteil and Friends last night in Silver Spring, Md., outside Washington. Strong performance and the sound was probably the best I've heard at the Fillmore, no doubt helped by venue allowing us to set up DFC rather than off to the side of board as is standard.
Yet listening to the recording reveals some really strange, annoying sound fluctuations. The volume will suddenly increase or decrease, giving a sorta "wavy" feel to certain passages. It's a bear to listen to.
A good example is Bertha:

- Doesn't seem to be a loose cable; I inspected L and R channels and the fluctuation is present in each.
- The recorder settings were not changed, though before the show I upgraded to the latest MixPre firmware.
- I noticed some swaying of the stand when the audience started dancing, but nothing extreme. Could it be phasing? If so, I've never experienced anything like that.

Could it be the venue PA? I didn't notice it at the show.I'd appreciate any observations, thoughts you might have.
