Bone Thugs-N-Harmony cemented their place among the greatest of 90s hip-hop with their release of “Tha Crossroads,” an elegy to lives lost in violence. “See you at the crossroads, crossroads / So you won’t be lonely,” grieves the quintet. The group has yet to surpass its successes from that golden age of hip-hop, but its distinct, melodic sing-rapping is still unmistakably Bone Thugs. These shows feel like warm reunions. —C.J.F.
