Before Gregg Allman passed away this summer, he recorded an album packed with new material. The posthumously released “Southern Blood” came out earlier this month. The heart-shattering album reflects on Allman's life as his terminal illness overtook him. We listen to the record and talk with Allman's longtime friend Chank Middleton and Allman's guitarist and band leader Scott Sharrard. We also hear from Allman's producer, Don Was.
