Trad music in clubs will likely begin to die unless it shares the stage with other musics, imo. People tend to like good music regardless its genre. The key is 'good'. Fewer and fewer will even listen to trad unless it is seen as an important music worthy of respect and to a degree veneration. If people are so narrow minded as to think of trad as a sacrosanct place rather than a respected member of a great art, then trad is doomed.
