Machinedrum is easily the most well-known alias attributed to American electronic musician Travis Stewart, who has also released material as Syndrone, tstewart, Neon Black, and Aden. Initially credited as Machine Drum (two words), he was one of the primary exponents of glitch-hop during the early 2000s, with acclaimed albums such as 2001's Now You Know and 2004's Bidnezz finding common ground between hip-hop rhythms and the tightly programmed experimental electronic sounds of IDM labels such as Skam, Warp, and Rephlex. His sound mutated as the decades progressed, with releases such as 2009's Want to 1 2? incorporating more club-friendly styles such as house, boogie, and dubstep. 2011's Room(s) marked a shift toward a vibrant hybrid of juke and U.K. bass styles, and 2013's Vapor City fused footwork and jungle. Stewart kept busy with collaborative projects such as Sepalcure (with Praveen Sharma) and JETS (with Jimmy Edgar), in addition to production work for the likes of Dawn Richard, Azealia Banks, and Jesse Boykins III, while his own albums, including 2020's A View of U, featured guests including Freddie Gibbs and Tigran Hamasyan.
