It was released by Arista Records on June 28, 1999, and reached number 1 on the Contemporary Jazz Albums chart, number 13 on the Internet Albums chart, number 17 on the Billboard 200 and number 27 on the R&B/Hip-Hop Albums chart.

[2] The third track features G's music overdubbed on Louis Armstrong's original recording, a move that was criticized by musicians such as Pat Metheny[5] and Richard Thompson,[6] who were angered by what they perceived as arrogance on G's part to use a song by Louis Armstrong for personal gain.

Additionally, some versions of the insert booklet of the Arista CD contained an error, attributing the writing of The Look of Love to Sammy Cahn and Jimmy Van Heusen, instead of the correct songwriters, Bacharach and David.
