Grammy-winning Anthony Hamilton is as old-school as R&B gets, and his music sounds as though he and Bill Withers, Donnie Hathaway, Al Green and Johnny Adams were alternating sets at a Memphis juke joint in 1974.

Rap? What's that?

There's still a vast audience for Hamilton's gorgeous, rootsy soul, which is why he co-headlines Foxwoods' Grand Theater Friday. He's on tour behind his latest album, "What I'm Feeling," with the lead single "Amen" hinting at the earthy gospel sounds that flavor the collection.

Also performing is Musiq Soulchild, an artist with similar classic influences but who also infuses plenty of hip hop into his work. It's clear he reveres acts from Sly & the Family Stone and Parliament to the Tempations, but his own formative years beatboxing for MCs on the streets of Philly bring a contemporary energy. Though his recent work hasn't fared as well as earlier platinum and gold efforts, he's still an 11-time Grammy nominee and has a fervently loyal fan base.

Anthony Hamilton and Musiq Soulchild, 8 p.m. Friday, Grand Theater, Foxwoods; $59-$158; 1-800-200-2882.
