A short lived Finnish pop rock band. The band was founded in the early 1980s when Martina Kallionalusta, a famous model at that time, tried a singing career. The other members in Martiz were professional rock musicians from Tampere, Finland. Martiz released one album in October 1982 but Kallionalusta left the band soon after. She was replaced by new singer Toni Lähteenmäki and the band's name was changed to Tiz.
