I don't think anyone is arguing that some monitor issues could make it very hard to perform. Just like when STP first reunited and he was botching lyrics, I would expect him to move around a bit and try to improvise. Or if all else fails, abort the song.
But I wouldn't expect the result as a person barely moving an inch, an emotionally void look on his face and a little more than monotone mumbling (I wouldn't call it singing) into the mic, and flubbing 1/3 of the BRAND NEW SINGLE.
My honest reaction watching the video (before reading comments) was that he was so completely off and started fussing around with the monitors more as a cover-up.
These guys are professionals. Am I supposed to believe that they wouldn't try to figure some monitor shit BEFORE carrying on to the next song? Or hell, maybe even acknowledge it to the crowd, instead of pushing forward with an absolute horror of a performance?
Who knows what's up, depression, anxiety, drugs, alcohol, meds, whatever. But something is clearly up. Just because he's been good many days and rebounded the next show doesn't necessarily make it case closed.
And seriously, are people really suggesting to forgive a full performance like this because its "par for the course" on a per tour basis?!? So you want a full audience to look at it and go "Eh, that's par for the course, oh well so much for my $50"
Besides being scared for Scott, I would be absolutely FURIOUS if this was how MY show turned out. I know it's a risk we take, understanding the performance won't be "classic Scott" or that he might not go on until 10pm. But we shouldn't be so dismissive of this performance JUST because it happens 2 or 3 out of every 20 shows...... I'm pretty sure that is EXACTLY the point Richard Patrick was initially trying to make (even if it was sticking his nose where it didn't belong).
Like everyone else, I just wish the best for Scott.
