If you're interested in being schooled in ancient Egyptian mythology and death metal, Nile offers an articulate lecture on both this week. Hailing from Greenville, S.C., the band blends pummeling drums with mathematical rhythms for an assault that quickly transitions from blast-beat to breakdown. Vocalist Karl Sanders belches folklore-themed lyrics over Arabic melodies and death metal chugging reminiscent of Dying Fetus. Nile is still supporting the 2012 album At the Gates of Sethu, but the third iteration of that tour will also commemorate the band's 20th birthday. The extended set will feature songs from Nile's entire career, including fan favorites the band rarely unveils onstage.
