4 Way Street is a live album by Crosby, Stills, Nash & Young, released in 1971 by Atlantic Records. It was the second album as Crosby, Stills, Nash & Young, after Déjà Vu in 1970. An earlier version of the band, with just Crosby, Stills, and Nash, had released the self-titled Crosby, Stills & Nash in 1969. The live recordings were taken from shows on the band's 1970 tour, with performances at the Fillmore East (New York City) on June 2 through June 7, 1970; The Forum (Los Angeles, California) on June 26 through June 28, 1970; and the Auditorium Theatre (Chicago, Illinois) on July 5, 1970.
Tensions between the band members were high during the tour, with their dressing-room fights becoming the stuff of rock legend, being referenced by Frank Zappa and the Mothers of Invention on their 1971 LP Fillmore East - June 1971. The tensions led to CSNY temporarily dissolving shortly after the recording of 4 Way Street. The album reached No. 1 on the Billboard 200, and was awarded a gold record.
