British rockers Foals found inspiration in voodoo practices while recording their latest album and even sent workers from their studio to collect animal bones for them to play as instruments.

Frontman Yannis Philippakis reveals the group wanted a primal influence on their third record, Holy Fire, and went to extreme lengths to achieve their desired sound.

He tells Britain's Guardian newspaper, "At one point we even made these poor studio interns collect bones. We were inspired by voodoo, these Haitian rhythms. We collected some ourselves, from butchers in Willesden High Road (in London).

"Mainly cows, I think - often they had gristle and cartilage on them, mainly cow and occasionally sheep. We had to order these big pots because one of the shoulder blades was too big! We boiled the flesh away so we could use them as percussion! We wanted to get primitive!"
