In 1999, the Boston, MA-based post-metal band ISIS released their EP The Red Sea. It was only the band's second proper release, as they had only formed in 1997, but it was an important moment in the band's development. They presented a lot of themes both sonically and lyrically that they would expand upon during the rest of the band. Isis eventually broke up in 2010 after releasing five LPs. This original ISIS shirt, in great condition, is from the band's 1999 EP The Red Sea.
