In 1995 Mark Rae fulfilled a long-term dream by founding Grand Central Records in Manchester. He first met sound engineer and producer Steve Christian when they both utilised the same rehearsal space in Ducie House in the Northern Quarter of Manchester. The first meeting took place when Christian, who is the production strength of the duo, walked past Rae's studio and informed him that his music was out of key. The pair embarked on a partnership that has seen them achieve critical and public acclaim for their work. In 1998, they released their debut album as Rae & Christian, Northern Sulphuric Soul. The Jungle Brothers and Jeru The Damaja both contributed to the album's songs, giving them an edge over other sampling groups of the late 1990s.
They undertook a heavy touring schedule, travelling with their own percussionist, double bass player, female vocalist, scratch DJ, saxophone, flute and rhodes players, to complement the skills of Rae behind the deck and Christian on guitar. Mark and Steve released their third album in October 2013 and took the new album on the road with varied line ups to match availability with the vocal guests involved. The album was recorded over the previous four years in Yorkshire in Steve Christian's studio with additional recording and writing under taken in Mark Rae's London studio. The album features the following guests: Ed Harcourt, Kate Rogers, Jazzy Jeff, Masta Ace, Mystro, Jake Emlyn, Gita Langley, Diagrams, Mark Foster, Agent 86, Mel Uye Parker and Pete Simpson.
