Jammer and Mumdance became friends and started working together in late 2007. Mumdance cites Jammer as one of his main influences and production mentors in this period, teaching him how to make grime and engineer vocals in his fabled basement studio in Leytonstone, East London. They toured a DJ / MC show around Europe together over the next few years and released numerous remixes and records in this time, including the “Tarahtid EP” on No Hats No Hoods and “Ten Man Roll” ft Boy Better Know, which was released on Jammer’s “Jahmanji” album in 2010.
