The staff at Polarity is truly the difference between an audio project just being recorded and mixed and one that takes on a life and personality of its own. Below are the people who make it more than just possible, they make it a creative fusion of the audio elements and the story which needs to be told.

Roger Wiersema

Mr. Wiersema's background includes an over 30-year involvement with music and sound that started in 1970, recording local high school bands in Indio, CA. During his high school days he built his first 4 track-recording studio in a friends garage. Realizing that if he wanted a career in the Recording Studio Business, he would either have to build his own or “know someone”, he pursued a career in Aeronautical Engineering, recording friends nights and weekends in the garage.
In 1976 he moved to San Jose, CA to continue his education at San Jose State University. During his first week at San Jose State he sat out on a mission to find out what music and sound was being done on campus. Going fist to Campus AV, where he was told he could show films, he went to Student Union AV and met up with the director. He told the director that he had built a garage studio and was interested in pursuing his interest in sound and music mixing. He was told, “Roger, I think we can use you.” He was hired on the spot and within 6 months he was the Audio Supervisor for Student Union AV.
His responsibilities included being in charge of all sound being done out of the Student Union, including lectures, dances and concerts. During his second semester he realized that the Student Union needed a bigger Sound System to better handle the bigger concerts that were coming though San Jose State. The money for capital purchases came from the Student Union Board of Governors, which he promptly got elected to as a “student at large”. The following semester, with some heavy lobbying, the money was allocated the build a new concert sound system.
While he was building the new sound system, he learned that San Jose State was going to offer a course in multi track recording in 1977; he was the first to sign up. David Porter (president and owner of Music Annex) taught the course at his studio and when David saw what Roger was building for San Jose State, David asked if Roger wanted to join Music Annex as its Chief Engineer and build a new facility in Menlo Park, CA. Roger was now in the Studio Business!
He continued 1978 going to school by day and building Music Annex Menlo Park nights and weekends. With the new Sound System done for San Jose State he was mixing bigger shows at San Jose State, up to the 5,000 seat Morris Daley Auditorium with groups like Pat Metheny, David Grissman, John Hartman, Steve Martin and Peter Gabriel. He graduated in 1979 with a BS in Aeronautical Engineering and a minor in Business Administration and assumed a full time career at Music Annex.
Music Annex was growing rapidly and he wore many hats as Chief Engineer. Some of his major accomplishments over the course of his 25 years at Music Annex include:

Toured North and South America as band's House Engineer.
Recorded and Mixed over 30 Albums.
Designed and Built 15 Recording Studios in the Bay Area.
