A couple of my pet peeves are things I call cultural colonialism and cultural appropriation. In some ways, they're close to being the same thing, in that it usually involves a person of one culture stealing from another for a variety of reasons. Quite a number of times it means a member of the dominant Western culture looking upon something from across the world, seeing it as exotic and then picking out the bits and pieces of it that amuse them without ever bothering to learn about the context they came from.
In some ways, it's a lot like putting on a police officer's uniform because you like the way it looks and then walking the streets. You may look like a cop on the surface, but the reality is you nothing of what doing the job involves. Most of those who are cultural appropriators are guilty of something similar. They dress themselves up in the trappings of a culture without knowing what it really means. Whether it is the pop star who picks up the sitar because it sounds cool or the new age musician who tries to make themselves sound more "spiritual" by using Native American flutes in their compositions, it amounts to little more than thievery.
However, music is supposed to be a universal language is it not? We're always hearing stories of musicians from different backgrounds getting together and being able to find common ground through the instruments they play even if they can't speak each other's language. There are also classical musicians who spend years studying and training in order to be able to play whatever music they chose, including pieces written by composers from other cultures and times. Their study have not only given them the technical ability to play a multitude of music and styles, but the means to understand the context they were written in. If a musician is willing to immerse themselves in a culture, or the music, then he or she will be able to play it, no matter what their own background.
Which goes a long way in explaining how a band from New Mexico in the United States can play the music of the Balkans and Eastern Europe and sound like they were born to it. On their most recent release, Cervantine, on their own L&M Duplication label and distributed by Midheaven, A Hawk And A Hacksaw perform eight glorious songs which not only sound like they're being played by people from their originating regions, but people steeped in its musical traditions.
