Yeah, back in the day, once Queensryche got to Empire, they all played to a click because of the screens. Prior to that, no click. If you have skillful musicians, you can pull it off well.
I love The Warning. And that makes sense and they are open about it. Frankly though, I wish they wouldn't do that. I get it - today, people expect the songs to sound exactly like the record. But for me, I'd just prefer them playing live and not worrying about it. Or bringing along a second guitarist to fill in those spots. Yes, it costs more money. And maybe these days, people (in general) don't care enough to justify the cost of another live musician.
But for my money, I'd prefer it.
I've softened a bit on my stance regarding Falling in Reverse. After hearing Sebastian Bach bitch about it on-air again recently, and getting tired of the rant, here's my bottom line. I get that laptops and running things through them is critical to some acts. Bottom line though, cancelling a show because of it is not okay. They should have budgeted for backups and replacements and had them ready to go. People can make any excuse they want on Falling in Reverse's behalf, but they got caught unprepared, and that's simply not okay.
I do go back on my much earlier comments about them just stripping it down and playing live with different arrangements. Some music you just can't do that, and they are one of them. So I get that. But in that case, the onus is on the performer to make sure they have technology redundancies (aka backups) in place to make sure they can play.
