I Know by Luther Vandross

I Know is the eleventh studio album by American R&B singer and songwriter Luther Vandross, released in August 1998 (see 1998 in music), and his only one for Virgin Records. It serves as his first album since fulfilling his contract with Epic after the release of his album Your Secret Love (1996). The album features guest appearances from artists such as Cassandra Wilson, Guru, Stevie Wonder, Brandy, Marcella Precise and Bob James. The album's title track earned Vandross two nominations at the 41st Grammy Awards including for Best Traditional R&B Performance for the aforementioned album and Best Male R&B Vocal Performance for the album's single. The album debuted and peaked at number twenty-six on the US Billboard 200 album chart, becoming his first album since Give Me the Reason (1986) to chart within the top 40 of the albums chart. The album also peaked within the top ten of the R&B Albums chart, reaching number nine. It was later certified gold by the Recording Industry Association of America (RIAA) in late 1998.
