Early life Born in Venice, Los Angeles, and raised in Santa Monica, Mike Muir is the younger brother of Jim Muir of the Dogtown skateboarding team. Jim exposed Mike to metal music as well as skateboarding. Muir attended Santa Monica College after being kicked out of school in the 10th grade. Career Muir has cited bands such as the Sex Pistols, the Ramones, Black Sabbath, UFO, AC/DC, Van Halen, Emerson, Lake & Palmer, Led Zeppelin, and Kiss as his early musical influences, and has said that he was introduced to funk music by former bandmate Robert Trujillo. Muir incorporated funk influences into a few songs by Suicidal Tendencies and into his funk metal side project, Infectious Grooves. Suicidal Tendencies Muir formed Suicidal Tendencies in 1980 when he was 17 years old. It originally consisted of Muir on vocals, Mike Ball on guitar, Carlos "Egie" Egert on drums, and Mike Dunnigan on bass. There were several lineup changes before Muir hired Grant Estes, Louiche Mayorga and Amery Smith on guitar, bass and drums respectively. In 1983, they released their self-titled album, with success sparked by the anthem song "Institutionalized", which would become one of the first hardcore punk videos to receive substantial airplay on MTV. They have since played tours and festivals worldwide. When No Mercy guitarist Mike Clark was hired as the band's second guitarist in 1987, Suicidal Tendencies began making a change from punk to metal, thus creating what would become crossover thrash, and later began adding funk influences to their music. Robert Trujillo, who was the bassist for Suicidal Tendencies from 1989 to 1995, was responsible for turning Muir on to funk music, and the pair would eventually form Infectious Grooves to play more funk oriented music. Cited as one of the most important crossover thrash groups, Suicidal Tendencies was active until 1995, but reunited a year later. Suicidal Tendencies has been touring or playing selected shows almost every year, and until the 2013 release of their ninth studio album 13, they had not released
