Not Otherwise Specified is a Heavy Progressive Rock project, which was founded by Craig Kerley in 2011 with the release of his first album Judgment. On this first release, Kerley wrote, performed and produced all aspects of the album. In 2014 Kerley released NOS's second album Projective Instruments. For the first time, Kerley included guest musicians on an album for specific parts, but continued to be the sole writer and primary performer for NOS's music. After the release of Projective Instruments, Kerley put together a live band and performed with them for the next three years. In 2017, the live band was dissolved and Kerley began work on NOS's third album Deadweight, which was released 2/1/19. While Deadweight was written and produced by Kerley, he relied more heavily on talented musicians in the Atlanta Prog scene. Many of these musicians make up the current, and hopefully final, lineup of NOS.
