Danny Boy or DB (b. October 31, 1977) is the stage name of Chicago native Danny Boy Steward, a contemporary African-American soul singer. He was signed to Death Row Records when he was just 14. He made his debut on 1994's Murder Was the Case soundtrack with the R&B charter Come When I Call (Produced by DJ Quik). In 1995, he released his first single entitled Slip N Slide (Produced by Reggie Moore and co-produced by DeVante Swing) with then unknown artist Ginuwine singing the chorus. The video was shot in Cabo, and also features scenes with 2Pac, Snoop Dogg, Nate Dogg and Tha Dogg Pound. Danny is best known for singing the choruses of the 2Pac songs I Ain't Mad at Cha, Picture Me Rollin' and Heaven Ain't Hard To Find on the All Eyez on Me album and Toss It Up on the The Don Killuminati: The 7 Day Theory album. He had recorded about 4-5 albums worth of music while on Death Row Records but none were ever released. Danny Boy also made an appearance on Tha Row's soundtrack to Eddie Griffin's Dysfunktional Family movie and also appeared on American Idol, but was disqualified due to continued internet promotion by his former label. He is currently working on some projects for his own label "Platinum Pearl" and currently resides in the suburbs of Atlanta, Georgia.
