XXI (band)

XXI (formerly, A Feast for Kings (AFFK)) is an American Christian hardcore, metal, and rock band, and they play a version of post-hardcore, progressive metal and progressive rock styles of hardcore punk, metalcore, and rock, with some more melodic hardcore and melodic metalcore elements. They come from Carrollton, Kentucky, where they were formed in 2010, with lead vocalist Eric Gentry. Eric's death in 2014 was the reasoning behind the band's name change, with 'XXI' (Roman numerals for '21') being Eric's age at the time of his death. Their first extended play, Hell on Earth, was released in 2014, shortly before Eric's death, and under their former name. The debut studio album, Inside Out, was released with Carson Butcher as lead vocalist on Tooth & Nail Records in 2015. This album was their breakthrough album on both the Billboard magazine Christian Albums and Heatseekers Albums charts.

Background

The band is from Carrollton, Kentucky, where they formed in 2010 under the name A Feast for Kings, with their members being lead vocalist, Eric Gentry; background vocalist and guitarist, Seth Weigand; guitarist, Jamie King; bassist, Robbie Barnett; and drummer Carson Butcher. After Gentry's death, the group changed their name to XXI to memorialize his age at his time of death. Their drummer went on to become their lead vocalist, and the bassist took over on the drums.
