Mats Öberg, born 1971 in Umeå, Sweden, has been living in Stockholm for many years, where he moved when he entered the Royal Academy of Music, where for two and a half years he studied individual music and, among other things, studied with the pianist Stefan Nilsson. Frank Zappa is one of Mats Öberg's idols. Together with drummer Morgan Ågren, Mats formed the group Zappatetoot early on, which only played Zappa covers. Then when Frank Zappa played in Stockholm in 1988, Mats and Morgon had the opportunity to meet him and also sit in the band. It was the beginning of a continued collaboration which meant that they both got to participate in the projects Zappa's Universe and Zappa at Lincoln Center in 1993.
