The legend of Buddy Guy continues, as the 72-year old guitarist promotes his first record ever to contain a complete collection of 100% original cuts, Skin Deep. Spawned from a childhood memory of his first encounters with racial divisions, Guy fuses his quintessential modern electric with his somber folk side—which should be an interesting sight amidst the wine-and-cheese picnickers of Ravinia’s fields. Gospel protege Jonny Lang, who wrote his first record at the age of 15, is still on a soul and funk kick from 2006's Grammy Award-winning Turn Around, which is slathered in Al Green sauce and choir as much as John Mayer blues-pop.
