Claim: Tim Mudde, the brother of a political scientist, was one of the two founders of a music group.
Evidence: Tim Mudde (born 23 February 1965), also known as Brigadier M or Sassem Tim, was active within the right wing radical movement in the Netherlands between the 1980s and the early 2010s. He is the older brother of the political scientist Cas Mudde, who studies rightist movements. In 1996 Mudde was one of the two founders of Brigade M, which initially was called Brigade Mussert referring to the personal bodyguards of Anton Mussert. Mudde was also a member of other RAC/Nationalistic bands: Dietse Patriotten, Die Fünfte Kolonne, Distrikt 217, H6, O.D.M., Oi-Die-Poes and Sassem Bootbois (later called Sassem Boot Boys). Mudde also had been involved with the RAC record companies Sassem Produkties and Muziek met wortels (Music with Roots). 
Brigade M was a Dutch right-wing nationalist Rock Against Communism-band from Sassenheim in the Bollenstreek. The driving force behind Brigade M had always been Tim Mudde. The band was founded in 1995 out of the ashes of the hardcore band Opel Kadeath.
