After a notorious 27-year absence, this legendary UK blues-rock guitarist (and, of course, co-founder of Fleetwood Mac) re-emerged in the late ’90s, forming the Splinter Group and recording seven albums from 1997–2004. There are magnificent chops and killer cuts galore on those recordings; here are the best, on CD or double vinyl: "Heart of Stone," "Burglar," "Hiding in Shadows," "Me and the Devil Blues," "Man of the World," "When You Got a Good Friend" and more. Double-vinyl edition has 17 tracks, while the 2-CD set boasts 32. Both feature Peter with Otis Rush, Dr. John and Paul Rodgers, and the 2-CD edition also features Buddy Guy, Hubert Sumlin and live renditions of "The Green Manalishi," "Shake Your Hips," "The Supernatural" and more!
