Petra is an American music group regarded as a pioneer of the Christian rock and contemporary Christian music genres and was, for many years, regarded as the "world's most popular Christian rock band". Formed in 1972, the band took its name from the Greek word for "rock". Though it disbanded formally in 2006, incarnations have played reunion shows in the years since and released two albums in November 2010, and in November 2017. In 2013, it reformed with a new drummer, Cristian Borneo, and recorded a new song titled "Holy is Your Name", before going back on tour.
With a style initially similar to The Eagles and Lynyrd Skynyrd, Petra's sound evolved into a more energetic, driving rock sound in the early 1980s akin to Foreigner, Styx and Journey. Throughout the 1980s and into the early 1990s, Petra was one of the world's most popular Christian rock bands, with each of its albums during that period selling hundreds of thousands of copies while the band sold-out arenas and regularly placed songs at the top of Christian radio charts.
