Hip-hop quintet Bone Thugs-n-Harmony set the future in motion with their '93 debut, Faces of Death. On the strength of that album, Eazy-E of N.W.A. signed the group from Cleveland, Ohio, to Ruthless Records. He was taken with their innovative style, which diverged from mainstream hip-hop in favor of intricate harmonies and a delivery and cadence inspired by jazz. Bone Thugs-n-Harmony's tribute to the late Eazy-E, "Tha Crossroads," won them a Grammy in '97 and they've sold over 25 million records to date. Infighting in the early 2010s led to the departure of several members, but since 2014 Bone Thugs-n-Harmony have been whole again and hitting the road. Tuesday their tour bus pulls up to the Bomb Factory, and it sounds like they've packed all their hits.
