With a slick style that incorporates soul's sexiness, gospel's harmonizing, and hip-hop's swagger, the Baltimore-born R&B group Dru Hill struck pop gold in the late ‘90s. Led by the serpentine vocals of Sisqó, Dru Hill have run through the emotional spectrum—wounded vulnerability on the lush “In My Bed,” strutting seduction on the Redman-assisted “How Deep Is Your Love,” besotted comfort on “These Are the Times”—over sinewy grooves that incorporate turn-of-the-millennium pop touches like glitchy synths and stuttering drums.
