Earlier this week, Sonic Youth appeared on Late Night with Jimmy Fallon, and as far as attention goes, Thurston Moore's t-shirt got plenty. In fact, Roots and -- in case you've forgotten -- Jimmy-Fallon-house-band member Questlove tweeted "thurston moore is wearing the riskiest tshirt ive ever seen on broadcast tv...gangsta move son." So what's all the hubbub about? Per The Frisky, The Village Voice discovered that the image -- which could basically be described as two naked dudes, one of whom is sitting atop the other's butt (I know. That's kind of hard to picture. You should have a look for yourself, here) -- is from an album titled I'm Your Chair from a band called Mokinox, which features a friend of Moore's. Mystery solved!
