Study: METALLICA's Music Calms Monkeys

Ian Sample, the science correspondent for, reports that METALLICA's music had the unexpected effect of calming monkeys when it was played to them as part of a recent study.

In the study, which was published today in the Royal Society journal Biology Letters, 14 cotton-top tamarins were played 30-second blasts of music while the researchers noted any changes in their behavior. The animals were played SAMUEL BARBER's "Adagio for Strings" and a soft piano piece from "The Fragile" by rock band NINE INCH NAILS, followed by METALLICA's "Of Wolf and Man" and an excerpt from "The Grudge" by rock band TOOL.
