Latest isn’t always necessarily the greatest, and if someone from 20, 30, 40, 50 years ago had an original idea but it languished in obscurity, for whatever reason, it’s new to you. Robert Johnson’s “Hellhound On My Trail”, with its downward chromatic riff, is pure doom; he just didn’t have a Marshall stack to play it through.Wow, a recommendation from the 21st century!
