I went to see Goldie Lookin Chain a couple of days ago – fun is hard to come by here in Shrewsbury, grab it where you can – and it was pretty good fun. (And the beer was cheap – £2 for Grolsch.)
But… the live experience of seeing rappers isn’t nearly as exciting as seeing a band. This is mostly a visual thing: talking/shouting into a mic doesn’t look nearly as dynamic as someone playing drums, or as interesting as someone playing a particularly tasty guitar solo.
Rappers can do the following: Wave arm(s) about / Jump up and down / jump up and down while waving arm(s). That’s about it. If the PA isn’t clear enough for you to hear every word – it wasn’t here, although it was pretty good – you’re really not going to be getting the optimum experience.
GLC try to get around this by having a lot of people on stage at once, all jumping up and down and waving their arm(s) about.
What? Why Bother?

( sorry – don’t know what came over me )…
wow – that’s *exactly* what it was like!
