Input: Question: Is the person Phang was a key influence to moving into record production still alive today? Passage:Phang started his reggae label Powerhouse in the early 1980s. His first hits were Little John's "True Confessions" and "Roots Girl", both released in 1983. He followed suit with Sugar Minott's "Buy off the Bar" and Barrington Levy's "Money Move" which were both two major hits that year. In the summer of 1984 he released Michael Palmer's "Lick Shot" which became of the biggest tunes that summer. Many of the most successful dancehall stars of the 1980s recorded for Phang. Half Pint's all-time greatest hit "Greetings" was released on Powerhouse in 1986. Conroy Smith's first song "Indian Lady" was also released on Phang's label. Other artists include Josey Wales, Freddie McGregor, Nitty Gritty, Tenor Saw, Little John, Brigadier Jerry, Barrington Levy, Admiral Bailey, Al Campbell, Charlie Chaplin, Cutty Ranks, Dominic, Echo Minott, Frankie Paul, Gregory Isaacs, John Wayne, Yellowman, Supercat, and General Echo. Phang mostly used riddims produced by Sly & Robbie, this gave him an advantage compared to other producers. His sound is characterized by the abundant use of reverb on the snare drums. However, by the late 1980s he stopped producing music. Phang was a key influence on Philip "Fatis" Burrell's move into record production.
