There are so many blogs out there, but here’s a look at just a few that are specialized:
I met Hungry Outlaw at Americanafest 2017. We went to several of the same shows. He covers both food and music, and posts videos.
Gary Hayes Country covers a vast number of independent acts in person, especially “outlaw country” types, including some not covered elsewhere.
Music City Maven specializes in east Nashville Americana, and posts many videos on YouTube of performance you won’t find elsewhere.
Kentucky Country Music is pretty self-explanatory.
Bluegrass Ireland also has a regional focus, and includes links to other sites.
