Listen to STICK HEAT by Toe Fat.
What's there to say about Toe Fat? That they have about the dumbest name ever thought of? I think that's probably a good shout. You have to give this tune thirty seconds to clear the dumb ukelele bit, then you get into pretty decent Sabbath-y, Deep Purple-y riffing. The vocals are proto-hair metal. All in all, it's an interesting track, veeeery much of its time (1970).
