The RH Factor is a progressive jazz group that combines elements of soul, jazz, funk, and hip-hop. It is led by jazz trumpeter Roy Hargrove and features many popular neo-soul and alternative hip hop artists. RH Factor blends a core band of two saxophonists, three keyboard players, two bassists and drummers, and two guitarists (including legendary soul session ace Cornell Dupree) with the best and brightest from the soul and R&B 'new schools' including D'Angelo, Badu, Meshell Ndegeocello, Steve Coleman, Karl Denson, Marc Cary, and two hip-hop MCs: Common and Q-Tip. 'I just wanted to open a door that would allow the musicians involved in jazz and the musicians involved in the R&B / hip-hop mainstream to form some music that would have no limit,' Hargrove explains. 'It's like a merging of those two worlds.'
