Pisces, Aquarius, Capricorn & Jones Ltd. is the fourth album by the Monkees. It was released on November 14, 1967, during a period when the band exerted more control over their music and performed many of the instruments themselves. However, although the group had complete artistic control over the proceedings, they invited more outside contributions than on their previous album, Headquarters, and used session musicians to complement their sound. The album also featured one of the first uses of the Moog synthesizer in popular music. Pisces, Aquarius, Capricorn & Jones Ltd. sold over three million copies, becoming the band's fourth consecutive album to reach No. 1 on the U.S. Billboard 200. No. 1 on the Billboard 200 for 5 weeks, from the issue of December 2, 1967. Wiki link
