The first time I saw or heard of OFWGKTA was a Complex.com article about their first show in NY on Dec 1, 2010. I've been listening to them ever since. I have seen their evolution from underground to well known in just months (thanks to Yonkers, performing on Jimmy Fallon,etc.).
OF frontman, Tyler The Creator has his second album Goblin being released on 5.10.11. Below is a song from the album entitled 'Tron Cat'. Enjoy.
