You don't have to be able to see (ie:you could be blind) to enjoy a good live band, yes it's about the music whether it's carefully crafted and produced in a studio or played well live on stage, if your at a live concert and just staring at the band then your not really enjoying the musical performance...
At a live show you should hardly notice the actual band on stage as you should be lost in a world of dance and listening to the music...
Yes most of these talentless wonder these days don't write their own music or lyrics or even have the skill to play an instrument, but even the biggest bands ever in the world (for example the Rolling Stones) never wrote all their own music, success for bands such as them was mostly down to the lead singers vocal talents and the band members ability and skill to play their own instruments...
Trouble is since the days of Stock, Aitken and Waterman, music (and I use that term loosely) has been manufactured to make as much money as possible by taking mostly talentless wonders to create a glossy image that is bought by a public who wouldn't know or appreciate good music if it slapped them in the face...
Point is, you can take someone off the street or one of those crappy so called talent shows on tv and and sell absolute shite to the vast majority of people these days just because they think it's the latest thing and is cool and trendy (a bit like the iPad), when at the end of the day it's nothing but crap bought by sheep because they don't want to be the odd one out or have the guts to stand up and say this is a load of BS...
