It’s hard to show the world you’re learned and erudite when you’re a T-shirt-and-jeans guy. Fortunately, this new T-shirt line ($16 to $23) cleverly pairs rock band logos with the greatest thinkers of all time. Whether you’re into the elegant mathematics of Pascal (done in the style of Poison), the natural philosophy of Darwin (Danzig) or the weird science of Carl Sagan (Slayer), Monsters of Grok has your back. And if your music tastes don’t run quite so heavy, they also nod to The Cure, Daft Punk and, yes, The Wu-Tang Clan. Pick up your thinking man’s logo T here.
