Background: Big Brother and the Holding Company is an American rock band that formed in San Francisco in 1965 as part of the same psychedelic music scene that produced the Grateful Dead, Quicksilver Messenger Service, and Jefferson Airplane. They are best known as the band that featured Janis Joplin as their lead singer. Their 1968 album Cheap Thrills is considered one of the masterpieces of the psychedelic sound of San Francisco; it reached number one on the Billboard charts, and was ranked number 338 in Rolling Stone's the 500 greatest albums of all time. The album is also included in the book 1001 Albums
Context: In September 1966, with no money to return to San Francisco, Big Brother signed a contract with Mainstream Records. They recorded four of the songs for the album Big Brother & the Holding Company in a studio in Chicago at the end of their four-week stint at Mother Blues on Wells Street. The club had paid them for only the first two weeks.' The remainder of the record was recorded in Los Angeles on December 12-14. Mainstream was known for its jazz records, and Big Brother was the first rock band to appear on the label. This may have influenced the final result, since the album sounded very different from what the band expected: acoustic and folk instead of heavy acid rock. The first single released was "Blind Man" b/w "All Is Loneliness," both from the album sessions, in July 1967. It was popular in the San Francisco Bay Area, but did not garner much national attention. A second single, "Down on Me" b/w "Call On Me" was released along with their self-titled debut album in August 1967, following the band's national success after the Monterey Pop Festival. The album debuted on Billboard charts on 9/2/67, peaking at No. 60. It stayed on the charts for a total of 30 weeks.  The Pop Chronicles criticized the record as difficult to find and "technically disappointing". "Down On Me" had a long gestation in the marketplace and finally debuted on the Billboard Hot 100 chart on 8/31/68, peaking at No. 43. It stayed on the charts for 8 weeks. Other singles from the album were released through the end of 1967 and 1968. One final Mainstream single, "Coo Coo" b/w "The Last Time," was released after the band's second album was issued by Columbia Records in November, 1968. These last songs were from the original album sessions, but were not included on the LP until Columbia acquired all of the band's Mainstream recordings and reissued the album in the 1970s.  The band then moved to Lagunitas, in Marin County, California, to a communal house. Later in 1967 they put an ad in the San Francisco Oracle with the apparent intention of moving back to the "City". The ad read: "Big Brother is returning to the city. Need rehearsal hall and a place to live. Write to B.B.& the H.C. at Box 94 Lagunitas."
