There are bad performances in all genre of music...the fast food syndrome is tipping over into everything else...people don't want to take time to learn the craft.
TASTE has something to do with our reception too. Some radio stations refuse to play females back to back...some people are into blues while others Celtic or blue grass and show disdain if the performer is boxed with their favorite label. All in all though I think that young musicians need to perform in order to get better. You never really begin to grow until you play to an audience. As musicians it ought to give some kind of JOY watching a young or new musician play...perhaps the goal should be to limit the performance to warm up act for seasoned musicians or limit the amount of time they are on stage. lol. I work with young people learning guitar and am always excited when they choose folk...A large percentage of people believe that 'noise' and lots of it gets them 'going' they don't have to think or really listen...lazy audiences. They find folk distasteful because it doesn't slam their senses and make them lose their edge...I suspect they also make love drunk.lol. You can't deal with that kind of mentality. They are always going to contribute to the illusion that folk is boring...
Let the inexperienced play so as to become experienced. We have a southern traditions music store that has jams every week and it gives the newbies an opportunity to mingle with the ol'timers...fantastic.
