The first Aquarius Records store was located in the Castro area of San Francisco. There were two early locations on Castro Street, including one next door to Harvey Milk's camera store. Chris Knab bought the store in 1972 and in 1978, he co-founded the independent punk rock and new wave music record label, 415 Records, with Harvey Milk's friend and his, Howie Klein. Around 1983, the store moved to 3961 24th Street, in Noe Valley. In 1996, new owner Windy Chien moved the store to 1055 Valencia Street in the Mission District.
