Don Carlos (born: Euvin Spencer) has had his greatest success singing with Black Uhuru, the reggae trio he formed in 1974 with two friends -- Rudolph Dennis and Derrick "Duckie" Simpson -- from the "Waterhouse" district in Kingston. Carlos recorded only one single with the group, leaving to pursue a solo career and to perform with a band, Don Carlos and Gold. Sixteen years later he returned and joined with Dennis and Simpson to resurrect the original trio. Their first album together, Now, released in 1990, helped Black Uhuru to recapture the popularity they enjoyed in the 1970s and '80s, though Carlos' involvement with the trio was brief. Shortly after helping Dennis and Simpson to record a second trio album, Iron Storm, Carlos resumed his solo career. While he's recorded some impressive albums, including his 1997 solo outing, Seven Days a Week, Carlos has yet to match the success he had with Black Uhuru.
