Back at One is the fifth studio album by American singer Brian McKnight, released on September 21, 1999, by Motown Records.

[1] While he enjoyed working on the record, McKnight was tormented by personal problems during the production process since he had fallen in love with someone else outside of his marriage with his wife Julie.

I was doing things then that I had never done before, that an audience had never heard or seen [...] I don't even listen to that record because it was the highest and lowest point of my life, because of this person.

"[1] Stephen Thomas Erlewine from Allmusic felt that with Back at One "McKnight has figured out a way to make his gospel-flavored contemporary urban soul sound fresh, mainly by keeping the focus on the songs.

At times, the material itself is not particularly interesting, but most albums have filler; what counts is the good stuff, and there's enough of it on Back at One to make it another solid effort from McKnight.

"[2] In a contemporary review, The Rolling Stone Album Guide wrote that "excepting the occasional boilerplate slow jam, One is McKnight's finest effort.

"[5] Writing for Billboard, Michael Paoletta found that "like its predecessor, 1997's Anytime, Back at One finds the singer keeping it sublime yet simple on an acoustic-based set.

Jerkins-produced "Stay or Let It Go" was released on a double single with the song "Win", McKnight's contribution to the soundtrack of the 2000 American drama film Men of Honor.
