What is it about Vampire Weekend that makes otherwise smart people stupid? Case in point: The friend who denounced VW as "nothing but a Graceland rip-off." Fun facts: African music did not begin with Paul Simon, white folks ripping off black music didn't begin with Vampire Weekend (see: all history forever), and no current band of honkies borrowing black musical tropes does so with more imagination and skill than Vampire Weekend.
