This is really fun music. It’s upbeat, it’s danceable (that’s a real word, it’s fine), and its lyrics often focus on stuff like politics, religion, culture, and drinking. Things that obviously go super well together in real life. Like a fender bender and a towing company. The genre also tends to focus on the pride of the working class, which I guess is common throughout a lot of non-Celtic punk music, so it makes sense that the Celtic version would hang on to a few features. As you’ve probably guesses by the name, Celtic punk is a fusion of punk with traditional Irish or Scottish music. The more general term folk punk does include Celtic punk under its umbrella, but typically when people talk about folk punk, they are referring to music that uses English or American or some other type of folk music as its base.
