Virginia-born R&B sophisticate D'Angelo has dominated the neo-soul movement since the '90s, his slow-simmering, molasses-soaked vocals lending every track a deeply felt maturity. Among his many collaborations, visionary harmonics add old-school flavour to hip-hop beats on J Dilla's “So Far to Go,” while his dizzying chemistry with Lauryn Hill makes “Nothing Even Matters” soar.
