On a good day, it's about a four hour drive from Baltimore to Brooklyn, and a soundtrack of James Brown's Star Time box set seemed like the perfect prelude to 77 Boadrum. Brown's endless, yelping variations on "give the drummer some" felt like prep work for absorbing the spectacle of 77 drummers, whatever they might end up playing. And "spectacle" proved an insufficient noun, with the nearly two hour performance that mystically celebrated 7/7/07 quickly becoming the stuff of dropped jaws, stolen breath, and "damn, you shoulda been there" urban legend.
