The Notorious Byrd Brothers is the fifth album by the American rock band The Byrds and was released in January 1968 on Columbia Records (see 1968 in music). Musically, the album represents the pinnacle of The Byrds` psychedelic experimentation, with the band blending together elements of folk rock, psychedelic rock, country music, electronica, and jazz on many of the songs. Of these disparate styles, the subtle country and western influences evident on a number of tracks pointed towards the full-blown country rock direction that the band would pursue on their next album. In addition, The Notorious Byrd Brothers saw the band and record producer Gary Usher making extensive use of a number of studio effects and production techniques, including phasing, flanging, and spatial panning. The Byrds also introduced the sound of the pedal steel guitar and the Moog modular synthesizer into their music for the first time on the album, making it one of the first LP releases on which the Moog appears.
