Explosions in the Sky is an American post-rock band, formed in Austin, Texas in 1999. The band is a quartet, composed of drummer Chris Hrasky and guitarist/keyboardists Michael James, Munaf Rayani and Mark Smith. The band originally played under the name Breaker Morant, then changed to the current name in 1999. They primarily play with three electric guitars and a drum kit, although James will at times exchange his electric guitar for a bass guitar and all three guitarists also add additional keyboard and synthesizer parts. The band later added a fifth musician to their live performances, largely to accommodate for these bass and keyboard parts. This role was occupied by multi instrumentalist, Carlos Torres, from 2010 to 2018, and reprised in 2024. The band has released eight studio albums to date; their most recent, End, was released in September 2023.
