As a rule, We do not post
ad hoc responses to ongoing debates, but you seem to be laboring under a serious lack of information regarding the use of a mixing board. Those "little signal lights" that mysteriously went off after the sound man adjusted his sliders are... say it with me now...
clipping indicators. In simplest terms, they turn red when the signal of a given channel exceeds the capacity of the output equiment. Consequently, the sound man (or lady) manually adjusts the faders over the course of the show to keep the levels of the various instruments, vocals, etc., sounding as clear as possible at any given time. Hence, the on-the-fly mixing of a LIVE show is a reasonably decent indicator that the sound has not been pre-recorded.
With regard ot the remainder of your rather embarrassing attempt at slander, re: Mr. Catalyst's guitar, We can assure you he was playing the proper notes and chords. Since 95% of all of the Sisters' rhythm guitar consists of variations on the E bar chord, it is a terribly simple matter to follow his fingers and compare with the corresponding sound emitting from the speakers. As it happens, We were in the front, slightly right of center, probably no more than a few feet from where you purport to have stood. Our vantage was at least equal to Our position at the Vegas show two nights prior, thus providing ample room for comparison. Simply put, the guitar was demonstrably live. There is no issue here, other than your own indignance at being subjected to a (horror of horrors!) night of material not culled exclusively from the deleted back catalogue.
Finally, in case you hadn't noticed, the Sisters are not the Jimmy Hendrix Experience. They do not regularly make use of deliberate feedback loops. Had you exercized your brain just a wee bit harder, so as to confirm or deny the evidence your optical sensors were delivering, you just might have realized that Chris was adjusting pre-amp volume, turning effects on and off, or otherwise fidgeting with his onboard kit. That's what live guitar players do. Especially the good ones.
BOX out.
Chairman BOX, unlike Chairman Bax, is not watching you.
Although we, much like the BORG, are a collective-
excepting only that our brains pulse with funk, love, and napalm.
If it was playback we'd get far better and more reliable soundquality, I reckon....
