Gladstone Anderson (18 June 1934 – 3 December 2015), also known by his nickname "Gladdy", was a Jamaican pianist, keyboard player, and singer, who played a major part in the island's musical history, playing a key role in defining the ska sound and the rocksteady beat, and playing on hundreds of recordings as a session musician, a solo artist, and as leader of Gladdy's All Stars, featuring bassist Jackie Jackson, drummer Winston Grennan, guitarist Hux Brown, and keyboardist Winston Wright.
As Harry J All Stars the band had a massive hit in Jamaica and United Kingdom with the instrumental song "The Liquidator" 1969 (and 1980).
Anderson's work was consistently popular in the late 70s too, as roots reggae, dub and sound system culture increasingly prioritised more conscious and deeply spiritual concerns.
