After his time with Pro Era, Warmsley began to explore a more experimental sound as a solo artist. In June 2013, he self-released "NW/WB", which showcased strong jungle and drum and bass influences and garnered a significant amount of press, including Spin, who included Bannon on their list of the 5 Best New Artists for July 2013. The attention drew the interest of British label Ninja Tune, which signed Bannon in October 2013. His debut long play, entitled Alternate/Endings, was released on January 9, 2014 to critical acclaim. Rolling Stone placed Alternate/Endings at number 15 of its 20 Best Electronic and Dance Albums of 2014.
