I'm guessing you've never heard of MINIVAN ROCK.  But I promise that you've HEARD Minivan Rock . . . even if you didn't know that's what it was called.

According to "Billboard", it's music from, quote, "the turn-of-the-century golden age of pop-rock radio hits."

It's "accessible, catchy, cleanly produced rock music built on sonic foundations of processed guitars and/or driving piano."

Think of it as the redheaded stepchild of Yacht Rock.
