Black Slate has been played on NTS over 10 times, featured on 13 episodes and was first played on 7 July 2014.

Black Slate was formed in 1974, including musicians from England, Jamaica, and Anguilla.[2] They backed several Jamaican singers, including Delroy Wilson and Ken Boothe on their UK appearances, and had their first reggae-chart hit themselves in 1976, with the anti-mugging song "Sticks Man",[1][2] also lined up with Disco Reggae Band under Disco Reggae Band & Black Slate. The record hit the Dutch[3] and Flemish charts as well, after being an underground hit in Antwerp discothèques. They toured the UK for the first time in 1978, and formed their own TCD label, having a minor hit with "Mind Your Motion".[1] They also backed Dennis Brown when he played live in the UK, and in 1980 their Rastafarian rallying call, "Amigo", was picked up by Ensign Records, and broke into the UK Singles Chart, reaching no. 9. A Dub Album "Ogima" (Amigo spelled backwards), was released in 1981. The follow-up, "Boom Boom" was also a hit, though less successful. An album, Sirens In The City, followed on Ensign the following year. The band released two further albums in 1982 and 1985.

After a ten-year hiatus they released a new EP, World Citizen, on 15 June 2013, with a UK and European Tour to follow. In November 2014, the band embarked on their first USA tour, with dates across California and Texas. The lineup featured original founding members Anthony Brightly, Chris Hanson, Desmond Mahoney and vocalist Jesse Brade. They have been working on a new album, Now And Then, for an official 2015 release on TCD Records.
