Jim Mullen is a Glasgow-born jazz guitarist with a distinctive style, like Wes Montgomery before him, picking with the thumb rather than a plectrum.
Jim Mullen was guitarist with Pete Brown & Piblokto! for two albums in 1970. He then played with Brian Auger's Oblivion Express, appearing on the band's first three albums together with future Average White Band drummer Robbie McIntosh, Mullen then joined Kokomo and later toured with the Average White Band.
It was while both musicians were touring the U.S. with AWB in the mid-70s that Mullen met up with tenor saxophone player Dick Morrissey, and throughout the 1980s, he found considerable critical, if not commercial, acclaim as joint leader of the pioneering British jazz funk band Morrissey–Mullen. Record producer Richard Niles, who produced the band's sixth album, It's About Time, would go on to produce three solo albums for Mullen.
