If you go to folk clubs or folk festivals you must expect to hear some political songs and some songs of social comment.That has been my experience of 50 years of involvement with folk music
if you want songs which are non political you will find that a good proportion of the repertoire is unsatisfactory.
if you want songs that just have good voices or good backing but are not political you are likely to be better satisfied going to pop concerts, that is not insulting anybody
if i w\ant to hear good improvisation, i go to a jazz club, i do not go to a country and irish concert.
i do not generally expect to hear as high a standrd of improvisation at a folk concert as at a jazz concert,[it might happen very occasionally] but that is not why i attend folk venues, horses for courses
