Released in January 1968, "The Notorious Byrd Brothers" album saw the band taking their psychedelic experimentation to its furthest extremes by mixing folk rock, country music, jazz, and psychedelia (often within a single song), while utilizing innovative studio production techniques such as phasing and flanging. The album featured contributions from a number of noted session musicians, including bluegrass guitarist and future Byrd, Clarence White. White, who had also played on "Younger Than Yesterday", contributed country-influenced guitar to the tracks "Natural Harmony", "Wasn't Born to Follow" and "Change Is Now". Upon release, the album was almost universally praised by music critics but it was only moderately successful commercially, particularly in the United States where it peaked at number 47. However, the album's reputation has grown over the years and today it is widely regarded by critics and fans as one of the Byrds' best album releases.
