? and the Mysterians (or Question Mark and the Mysterians) are an American garage rock band from Bay City and Saginaw in Michigan, initially active between 1962 and 1969. Much of the band's music consisted of electric organ-driven garage rock and an enigmatic image inspired by the 1957 Japanese science fiction film The Mysterians. In addition, the band's sound was also marked by raw-resonating lead vocals of "?" (Question Mark, the stage name of Rudy Martínez), making Question Mark and the Mysterians one of the earliest groups whose musical style is described as punk rock. Their music and imagery were highly influential on later bands.
