65daysofstatic (also known by the abbreviations 65dos, 65days, or simply 65) are an instrumental post-rock and math rock band from Sheffield, England, comprising Paul Wolinski, Joe Shrewsbury, Rob Jones and Simon Wright. The band has released five studio albums and a soundtrack: The Fall of Math, One Time for All Time, The Destruction of Small Ideas, We Were Exploding Anyway, Wild Light and Silent Running, respectively.
Initially, the band interspersed heavy, progressive, guitar-driven instrumental sections with live drums and off-beat sampled drums akin to those of Aphex Twin, although since their second album they have developed their work to include keyboard parts.
