I’m really surprised I’m the first to upload Savoy Brown on here, especially considering their history. They were one of those pioneering 60s blues bands who, alongside Chicken Shack, Fleetwood Mac, and others, were a key influence on the likes of Zeppelin and especially Sabbath. They also seemed to get a bit harder with each subsequent release. This one here, Hellbound Train, is one of their finest, if only for the title track alone.
