Schmier: "It's just a sad fact that a lot of rock and metal bands nowadays are using backing-track tape for backing up the band, with vocals, and strings, and backing vocals, and guitars, and keyboards, and all kinds of sh!t. For me, when you play live, there should be no backing track. A lot of vocalists also back up their whole lead vocals with backing tracks nowadays, and that's a very sad fact. In that song 'Elegant Pigs', I'm asking 'What the f%&# happened to rock 'n' roll?' It's lying. The fans don't know when the band is cheating, but for me it's a f%&# topic that I want to talk about. A lot of my musician friends don't like the fact that I'm talking about it, but I don't care. For me, rock 'n' roll is a holy spirit, and it's a f%&# no-go to do this in this kind of music. A lot of pop bands have been doing this for generations, but not in heavy metal. Yeah, I'm dealing with stuff that is basically bothering me. It's also a big release for me to write lyrics — kind of my own psychological session."

I forgot to add that some bands, for sure Shine Down, had multiple backing tracks.
