Metalachi performs rock and metal songs using instruments and styles from the mariachi tradition. Their covers include selections from Metallica, Led Zeppelin, and Faith No More. Here's their rendition of a Guns N' Roses classic. The brass instruments are really effective with this song, and the lead singer does a good impersonation of Axl Rose at the end.

While the brass was good, the hidden gem for me was the violin solo.
