purists

A purist is someone who likes things done the traditional or original way, without any changes or additions.

You might hear people say that a musician is a purist because they only play music on old instruments, like classical guitars and pianos, and never use modern electronic effects. This means they really care about keeping the music pure, just like it was meant to be played many years ago. In fact, many artists in different fields are called purists when they stick to what they know best and don't try to mix things up with new ideas or styles. For instance, a chef might be considered a purist if they only use traditional recipes without any creative twists.
