The Black Sea was formed from the ashes of Frodus in 2002 when Frodus's Shelby Cinca and Jason Hamacher decided to continue playing together. At the time they recruited Fugazi bassist Joe Lally to play bass. At the time they weren't sure on if the musical endeavor would go beyond just playing music. In February 2002, Hamacher left for a 3 month excursion to Eastern Europe and Turkey after recording drum tracks for the pair.
Cinca and Lally put together songs to the drums and decide that there's more to this than just a 'fun project'. Hamacher, while in the Syrian plains, suggests the name The Black Sea because of the region he was in.
In July, under the name The Black Sea, they recorded 3 songs and later released an EP on Lovitt Records. The three took an extended vacation in the beginning of the year and returned to America and recorded a copious amount of material. The Black Sea had finished a majority of their full length album DISCONNECTION_IMMINENT when they received emails stating that the band name "The Black Sea" was protected under ASCAP and legal action would be taken if they did not change their name.
Soon afterwards, Joe Lally moved west (location unspecified) and the band changed its name to Decahedron.
