These 2 groups alone are enough to justify the SACD format. Listening to Subterranean Homesick Blues right now and comparing it to the remastered redbook - my god what a difference! Redbook is just the voice and a distant indistinct band, while the SACD has the backing band fully on stage with Dylan.
And the Police? Wow, you can actually hear that those are real, live, flesh and blood instruments they are playing! Wow.
