Told my mother his name and she just said Nice and Slow, like she'd been waiting years to say it. Didn't know the face till the clips came round today.

Manuel Lonnie Seal Jr. was an American songwriter, record producer, multi-instrumentalist, arranger and vocal coach whose partnership with Jermaine Dupri helped define the sound of So So Def and a generation of R&B and pop hits. He died on 27 September 2026, one day after his 66th birthday. The cause of death was not publicly disclosed.
Born in Chicago on 26 September 1960 to Manuel and Betty Seal, he moved with his family to Freeport, Illinois, when he was three. Both parents had musical backgrounds. His father sang and played multiple instruments in a band. His mother sang in the church choir and later worked as a school teacher. Seal began piano lessons at age five. When he was about ten, his father left the family and returned to Chicago. Betty Seal worked hard to secure a home for Manuel and his two younger sisters, a house the siblings later still shared. At grade school he took up the flute when guitar was not offered, while continuing to excel at piano. By high school he had formed a band, played bars while still underage, and built a Midwest following as he traveled and sharpened his skills on piano, keyboards, guitar, synthesizer bass, saxophone, organ and flute.
A manager found Seal while he was working with Grammy-winning singer Ann Nesby, a fellow native of the same small Illinois towns. Meetings in Los Angeles led to a short stretch at BMG before he returned to Freeport. Further meetings took him to Atlanta. There, Dupri discovered him in a hotel lobby playing piano and singing to a gathering crowd and signed him on the spot. The discovery story became part of So So Def lore: a working musician from Freeport suddenly plugged into Atlanta's rising hit factory.
Seal began work with Al Jarreau, then scored his first major success with Xscape. He wrote, produced and arranged much of the group's debut album Hummin' Comin' at 'Cha (1993), including the ballad Understanding, which he wrote in a hotel room between sessions. Two number-one R&B singles and a top-ten cut from that project announced him as a writer who could deliver both street-facing rhythm and quiet-storm melody.
He composed the music for Da Brat's Funkdafied (1994), the first album by a female solo rapper to reach platinum status in the United States, and sang on the title single. On TLC's CrazySexyCool (1994) he wrote three songs for an album that sold tens of millions worldwide. Usher's My Way (1997) went multi-platinum; Seal wrote seven of its ten tracks, including You Make Me Wanna..., My Way and Nice & Slow, songs that helped turn Usher into a global R&B star. With Mariah Carey and Dupri he co-wrote Always Be My Baby for Daydream (1995), a mid-tempo staple that remained on radio for decades. Later credits spanned Jagged Edge, Aretha Franklin, Destiny's Child, BeBe Winans, LSG, Johnny Gill, George Benson, Tamia, Aaron Hall, Mary J. Blige, Monica, Lionel Richie, Ashanti and Gerald Levert.
In the mid-2000s he co-wrote My Boo for Usher and Alicia Keys on the special edition of Confessions, and won the Grammy Award for Best R&B Song for Mariah Carey's We Belong Together from The Emancipation of Mimi (2005). The single topped the Billboard Hot 100 for fourteen non-consecutive weeks. He continued on Carey's E=MC2 (2008), Usher's Here I Stand (2008), and Janet Jackson's 20 Y.O. (2006) and Discipline (2008). Over his career he received thirteen Grammy nominations and one win. Dupri nicknamed him Big E and later said Seal was the first person who truly understood him musically, calling him a co-creator of the So So Def sound.
Away from the biggest chart weeks, Seal also worked as a vocal coach and arranger, and appeared in industry panels and studio features that showed a craftsman more interested in the board than the red carpet. Collaborators remembered a musician who answered ideas with harmony and feel, not with ego. That reputation, as much as any single certificate, explains why Atlanta writers and singers treated him as a quiet reference point.
Seal died on 27 September 2026. Dupri announced the death on Instagram the same day, writing that they always ended conversations by saying I love you, and asking that Seal's soul rest in peace. Industry tributes followed from peers including Bryan-Michael Cox. He is remembered as a quiet architect of modern R&B whose melodies remain on radio and playlists decades after the first So So Def breakthroughs.
