“When we talk about 'Firepower,' we're talking about the fire and power of heavy metal to prevail and endure difficulties. 'Children of the Sun,' is, to some extent, about climate change and the ecosystem... We want to deliver a message to the people without being too much of a teacher.”

English heavy metal singer

Rob Halford is an English heavy metal singer and the lead vocalist of Judas Priest, a role he has held since 1973. He was born Robert John Arthur Halford and is known for his work in heavy metal across several decades. He is especially recognised for his powerful, wide-ranging operatic singing style and for the leather-and-studs image that became closely associated with him and with heavy metal more broadly. His other projects have included Fight, Two, and Halford, and he received the 2010 Grammy Award for Best Metal Performance.
