i think technical skill is a different thing from being a good musician. you can be the worlds greatest guitarist but still be a poor musician imo. a good musician is someone who listens to what's happening around them and works to the music not to their skill. a band is a group effort and not a showcase for solo's. if a guy doesn't know his instrument very well but what he can play fits the style of the band then there's no problem. people can learn as they go but a band lives and dies on how the members fit together.
so technical skill gets a thumbs down but the ability to listen to music around you and play to that gets a thumbs up
