I live in Nashville and there’s all types of music here but the emphasis for tourists is country
Everything from old country to pop country you just have to do your research on the best spots!
A lot of more popular places do more “marketable” pop because they’re artists/bands are trying to score record deals. But there’s definitely old country music
Definitely visit the country music hall of fame if you’re in town and do the trolley tour (lots of info on all types of country music!)
