Lacksley Castell was born in 1959, although some sources claim 1962. Growing up in Kingston's Waterhouse district, along with artists such as Black Uhuru and The Travellers, Lacksley recorded in what was known as the "Waterhouse style". Castell became friends with Hugh Mundell who helped both him and his friend Junior Reid to get started in the music business. That resulted in Castell's first single releases in 1978, "Babylon World" and "Love in Your Heart", recorded with Augustus Pablo. In 1979, he recorded "Jah Love Is Sweeter" at Lee "Scratch" Perry's Black Ark Studios, which was a pre-release reggae chart hit in the United Kingdom in August 1979, with "What a Great Day" (produced by Prince Jammy) making the top five of the reggae 12-inch singles chart the same month.
In 1980, Castell recorded the Jah Fire album with Hugh Mundell, produced by Prince Jammy. He also provided backing vocals on Sugar Minott's Black Roots album and had a further 12-inch hit with "African Queen" that year. His first solo album, Morning Glory, was released in 1982 on Robert "Flacko" Palmer's Negus Roots label, who also produced the record. This was followed by a second album, Princess Lady in 1983, co-arranged by Dean Fraser and mixed by Neil "Mad Professor" Fraser. Castell was also credited as arranger on fellow Negus Roots artists Sly & Robbie's 1982 album, Dub Rockers Delight, which consisted of dubs from his Morning Glory album. Dubs from the Princess Lady album were included on Mad Professor's In a Rub a Dub Style.
Lacksley died in 1983 of an asthma attack after being weakened by tuberculosis (some sources also claim stomach illness was the cause of Castell's death). His two albums were re-issued on CD in 2005. Lacksley Castell Facebook page exists, maintained by his brother Trevor Castell.
