"4 Way Street" is a live album released in 1971 by which of these bands?

"4 Way Street" is a live album by Crosby, Stills & Nash, and their second album as Crosby, Stills, Nash & Young.

It was originally released as Atlantic Records SD-2-902, shipping as a gold record and peaking at No. 1 on the "Billboard" 200. A document of their tour from the previous year, the live recordings presented were taken from shows 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.

At the time this album was recorded, tensions between the band members were high, with their dressing-room fights becoming the stuff of rock legend, even being referenced by Frank Zappa and the Mothers of Invention in their 1971 LP "Fillmore East - June 1971". The tensions led to CSNY dissolving shortly after the recording of "4 Way Street"; they would reconvene for a stadium tour in the summer of 1974.

Crosby, Stills & Nash (CSN) was a folk-rock supergroup comprising the American singer-songwriters David Crosby and Stephen Stills and the English- American singer-songwriter Graham Nash. When joined by the Canadian singer-songwriter Neil Young, they were known as Crosby, Stills, Nash & Young (CSNY). They are noted for their intricate vocal harmonies and lasting influence on American music and culture, their political activism and their tumultuous relationships.
