Formed in 1999 in Austin, Explosions in the Sky helped pioneer the genre known as post-rock, a form of experimental rock which uses traditional rock instruments to produce instrumental soundscapes. In fact, they're still probably one the most recognized in the genre, alongside Mono, Godspeed! You Black Emperor and Sigur Ros. Explosions combine shimmering cascades of reverberating guitar riffs with echoey roll drumming for a style they refer to as "cathartic mini-symphonies." The band had already seen plenty of success with the release of their first three albums, but it was their heavy contribution to the Friday Night Lights soundtrack that gained them major mainstream attention — and an audience that catapulted them far away from the trenches of underground music. Carving a path for a generation of post-rock bands to follow (including San Marcos’ This Will Destroy You and San Antonio’s Bright Like The Sun), Explosions In The Sky continue to write ethereal and thunderous compositions that have been entrancing audiences for almost two decades.
