Raphael Saadiq’s fantastic 2008 solo album, The Way I See It, is a tasteful slice of old-school, Smokey-style R&B, but live Saadiq turns up the heat. Backed by an ace band, he shows it’s possible to be classy and sexy. And he ain’t too proud to do his old hits from the Tony! Toni! Toné and Lucy Pearl days, either. Today he heads up a birthday party for the concert company Giant Step; Aloe Blacc opens.
