Not all venues that cater to new talent need to be hidden in a warehouse. A sold-out show at the legendary SOB's has been a hip-hop rite of passage for decades. Remember when Kanye West bragged about the "party at SOB's and we packed the crowd"? Drake's over-capacity show here was the talk of the city. Both J. Cole and Iggy Azalea sold out the room not long before earning support slots for Rihanna and Beyonce (respectively) on their world tours. At SOB's, with a standing capacity of only 450, you can hang out by the bar all night and still have a better view than front row at MSG.
