Just looking for some input/ideas on a show I recorded a couple weeks ago. Los Lobos did an 'acoustic' show at the Symphony Center in Chicago, which is a nice sounding venue but with some complex acoustics to record. The recording did not come out quite as I'd hoped; so I was looking for some input should I come across a similar situation down the road.
Here's a pic of the stage:
For those not familiar with the venue, it is what you would expect of a concert hall, designed for full-on acoustic productions of symphony, classical recitals, opera, etc. For the LL show, all the tiering that normally seats the third & fourth rows of the orchestra was retracted; and the rear sectors of the stage were all covered in black cloth, with audience seated behind (as in the picture). As you can tell, the stage is all wood; and the seating area has four levels (mezzanine, boxes, lower tier, upper tier).
The band's instruments were run through DI's into the PA; but there were two small amps (Fender Deluxe Reverb's) for some bajo & tres parts. Conrad alternated between a guitarron through DI and Gibson bass through a small amp. Also there was a drum kit that also included bongos, congas, a
cajon and a set of timbales. The drum kit and the amps were all placed behind lexan baffles and mic'd. The PA was suspended left & right in a three-panel configuration, splaying progressively upwards following the tiers. The soundboard was located in the center box of the box tier.
I ran KM140's (ortf)>MME>DA-P1, with the mics clamped in front of the soundboard (about 85' direct line from the center of the stage setup), raised to about head height equal to a person sitting in the adjacent boxes. There wasn't much of a soundcheck; so I didn't get a chance to get a feel for any adjustments to be made. Still, sitting in the box next to the mics, the sound I was hearing was very full; and I was excited to hear the results.
When I listened back to the tape, the instruments that went DI came out nicely; but the instruments fed through amps, though having sounded great during the performance, were kind of distant in the recording. Vocals were also down a bit; and the drums/percussion...they were real "interesting." Soft passages were OK; but as the drums were played harder, I started picking up (on the recording anyway) a slap off the back wall which seemed to mud out the drums.
So, all this to ask: what could I have done to improve results? Would it have been better to run omn'si from that location, to better pick up some of the ambient reflections of the room? There was nowhere else that I would have been allowed to set up openly; and I don't know how soon I'll be in a similar place to 'experiment.' Of course, I should have had some clue as to what was facing me, as the venue itself had a dozen mics suspended over the stage pointed in every direction. I remember thinking it'd be fun to have had all those sources to play with.
One other thing. After listening to the recording, I once again realized what an amazing thing the human auditory system is, because what I captured and what I heard sitting right next to the mics was so dramatically different.
