Rock Show? Worship? What's the difference these days. What's "good" worship?

 

On the twitter this week this picture was posted by a church-leadery-business-thinker-type-of-person I ended up following along the way somewhere. The caption said this: "Top picture is from the inside cover of my new #Rush DVD, bottom is #OneLife worship from tonight."

Now...I can't tell for certain but it sounds like that's a good thing to him.

Is it really a good thing (or is it a bad thing or doesn't it matter) that our worship services look like a Rush show (or any other rock concert for that matter)? Do our toes have to tingle & chests feel the thump of the bass & the chord progression have to be catchy like a rock show? Hmm...
