Spaghetti westerns is the nickname for a broad sub-genre of western film that emerged in the mid 1960's, so named because most were produced and directed by Italians.
They were filmed in regions of italy but also Spain- this links in with the concept that my song has a spanish feel to it, so incorporating the western aspect and Spanish sound could actually really work
Typical themes in Spaghetti Westerns include the mexican revolution, a focus on revenge and the myth of the hunter/bounty killer. So even though its a different culture producing the films, they still cover the same ideas of revenge, justice, honour and also the lone figure idea. It just hows the western has universal appeal.
One of the most famous spaghetti Westerns was the Dollars Trilogy.
