Megadeth‘s Dave Mustaine says bands who rely on pre-recorded tracks during their live performances are being “lazy.” He recently told Kerrang! Radio, “I don’t think there’s anything wrong with using supplements for songs and other sounds and stuff like that if you can’t play ’em live. If you can play it live and you’re being f**king lazy and you’re seeing whatever just happened a couple of days ago with one of those big bands, and the singer… the tape started and the drummer wasn’t playing or something . . .” Mustaine is referencing a technical mishap by KISS drummer Eric Singer during the band’s concert in Antwerp, Belgium earlier this month.

He added, “I’ve always done the background singing on the records until — maybe about 10 years ago, we started having another person come in and help supplement the vocals because it’s just not my bag to be singing stuff that I’m not gonna sing live. I sing when I sing live on the records as much as I can.”

Megadeth will take the stage at the Barcelona Rock Fest in Spain on Saturday (July 2nd).
