JJ Grey & Mofro is a unique Southern rock band with origins in Jacksonville, Florida, and that will be performing in Salt Lake City on Sept. 23 at the Eccles Theater. John “JJ” Grey and Daryl Hance, who is no longer with the band, met in Jacksonville through their jobs at an air conditioning company, and their friendship grew through their appreciation for music. After a deal with a record label in London fell through, both Grey and Hance returned to Jacksonville, where they started Mofro, a name Grey coined to explain the sound of the band.

JJ Grey, the singer, delivers each song with unparalleled soul and passion, which are matched by the band, Mofro, playing the background music. Together, JJ Grey’s singing and Mofro’s unequivocally beautiful guitar, drum and jazz combinations produce a harmonious and graceful tune.

JJ Grey & Mofro have released quite a few studio albums, including Blackwater (2001), Lochloosa (2004), Country Ghetto (2007), Orange Blossoms (2008), Georgia Warhorse (2010), This River (2013) and Ol’ Gory (2015).

It is difficult to pinpoint one genre for JJ Grey & Mofro as the group’s music spans a combination of blues, soul, rock and funk. The latest album, Ol’ Glory, is a testament to the band’s continually evolving, complex style. Amazingly, every song is written by JJ Grey and is a reflection of his surroundings or regions in Jacksonville. Grey attributes his writing style to artists like Big Bad John and Jim Reeves, and he credits soul artists like Otis Redding and Toots Hilbert as poignant influences upon his musical style.
