If it doesn’t have guitar, bass, drums (and/or other instruments) and a singer (or a singer on an instrument too) then it’s likely not worth watching.
Go to a real rock n roll/metal, blues or blues-rock-jazz, or any real live band music for some entertainment, not that television craps with a jerk on stage signing or lip syncing to a recorded soundtrack. Horrible stuff and I can’t understand how people can’t watch or listen to that garbage with no backing band.
Yeah, they had ALL of that on stage, but if they’re all just pretending to play to a track then it’s just for show. Almost all the music shows in the old days used to do that and they were all very polished at it. I thought they stopped doing that a long time ago.
