VINYL FORMAT. "With Another Side of Bob Dylan," Dylan began pushing past folk, and with "Bringing It All Back Home," he exploded the boundaries, producing an album of boundless imagination and skill. And it's not just that he went electric, either, rocking hard on "Subterranean Homesick Blues," "Maggie's Farm," and "Outlaw Blues," it's that he's exploding with imagination throughout the record. After all, the music on its second side ?- the nominal folk songs ?- derive from the same vantage point as the rockers, leaving traditional folk concerns behind and delving deep into the personal.
