Butcher Knives merge several musical genres into one unique style, specifically old-school rockabilly, punk and gypsy. Their single “Tell Me Why” features folk instruments such as fiddles, accordions and harmonicas, but are used in a typical punk rock manner. The group itself is made up of both genders, and has members from foreign countries like Morocco, Israel and Colombia, as well as from the United States. The international influence can definitely be heard in their songs and adds to their genre-blending style. They will be playing at Piano’s in NYC on Dec. 21.
