The 11 songs on Olustee, the latest offering from blues-rock act JJ Grey & Mofro songs range from the raucous Wonderland” to "Sitting on Top of the World," a song driven by woozy horns. It's an ambitious effort, and the uptempo songs should translate well to the stage. The blues-rock act comes to the Agora tonight at 6:30. Judith Hill opens.
