Soul experimenter Raphael Saadiq's catalog is full of intriguing byways. His work with Tony! Toni! Toné! includes “Little Walter,” an inventive new jack revision on the old blues cautionary tale, and the sprightly, hip-hop sampling funk of “If I Had No Loot.” “Heart Attack” may be the best slice of scratchy funk that Sly & the Family Stone never wrote, and the bubbly R&B of “Faithful” is guaranteed to make your hips sway in appreciation.
