it is more important to have suitable places to sing the music , if you sing the music in places where no one is interested, you are demeaning the music you are also not able to perform it as well,good performance is a two way thing it requires interaction.
I have got to the point now where i would rather sing for my own pleasure at home ,or as i did yesterday sitting on a deserted beach at dunmanus bay in the sunshine , than sing at an open mic or to be booked at a totally unsuitable venue, that is why i no longer take gigs on new years eve. there is your answer.
