Peter Mazich (born October 25, 1964) is an American punk rock organist best known for his work with Mike Watt And The Secondmen. A classically trained pianist, Mazich became interested in playing the organ after hearing the classic Deep Purple album Machine Head; he also counts jazz organ pioneer Jimmy Smith as an influence. Mazich joined Watt in recording The Secondman's Middle Stand in January and February 2004; the album was released in October of that year. Mazich proceeded to fulfill a lifelong dream of his when he became an endorsee of Hammond Organs during the tour.
