The Florida songwriter and his industrious sidemen specialize in hard-riffing Southern rock, no-nonsense swamp funk, and blue-eyed Memphis soul. Grey's music doesn't mind taking its sweet time, and his harmonica moans like a restive spirit through "Blackwater," the seven-minute title track from his 2001 debut. Grey's gritty voice is perfect for storytelling songs like "Ho Cake," a rambunctious paean to soulful home cooking. But it's hot and steamy front-porch boot stompers like "99 Shades of Crazy" that make this environment-loving good ol' boy a crowd pleaser both up north and down south.
