Late to this thread, but A Hard Road is my favourite Mayall album. I don't know what I can add about the sound over what others have already written, but there's something about it that strikes me harder over the Beano album. Yes, that's a harder rocking record, but A Hard Road's got a bluesier vibe IMO, and The Supernatural...wow. Unparalleled and clearly ahead of its time. A Hard Road is a better recorded album, too, at least as it sounds on my mono copy.
