Pop/Soul/blues trumpeter Willie Mitchell is one of several prime movers in the development of the style in the 1960s and 1970s. A representative Memphis soul artist is Al Green, who recorded at Hi Records. Several Stax artists also sometimes performed in this style, including Booker T. & the M.G.'s, who also sometimes played a harder-edged Southern soul. After the rise of disco in the late 1970s, Memphis soul declined in popularity.
