Her first full-length concert in twenty years, One Voice began as a benefit performance at Streisand's Malibu, California home on September 6, 1986.

[2] The album contains Streisand's only recordings of two Harold Arlen classics "Over the Rainbow" and "It's a New World" as well as her version of "America the Beautiful".

The concert and album raised millions for Democratic candidates and for charities committed to anti-nuclear activities and the preservation of our environment, civil liberties, and human rights.

The One Voice album, VHS home video and NTSC Laserdisc of the concert were released in April 1987.

The concert footage includes some of the many celebrities in attendance, as well as bits of Robin Williams performing an ad-libbed monologue to open the show.
