I would like to suggest that maybe the venues you choose are not the ones for listening. Most folk clubs (think original accoustic music written and performed by the songwriter) are considered listening rooms. For examples check out unclecalvins.org, a coffee house in Dallas since 1982 which has shows most Fridays. OK I am one of the sound guys there. Most venues like this cater to the singer songwriter who are usually artists who tour nationally. Also look up the Kerrville Folk Festival which has been ongoing since 1972. Go to Calvins website and link to the artists for examples of their music. You might not like them all, but the venues they play have patrons who actually listen to the music. Find these type of venues in your area. Good luck and happy listening.
