Cream was among the most successful acts of its time, selling more than 10 million records. But by 1968 Baker and Bruce had worn each other out and even Clapton had tired of their deafening, marathon jams, including the Baker showcase "Toad," one of rock's first extended drum solos. Cream split up at the end of the year, departing with two sold-out shows at London's Albert Hall. When told by Bulger that he was a founding father of heavy metal, Baker snarled that the genre "should have been aborted."
