Joey Bada$$ was in Beantown last night for a show at Boston University with his Pro Era crew, and also Chance The Rapper, who he recently linked up with on "Wendy N Becky." Watch above as Joey keeps the crowd hyped during a performance of his 2012 single "Waves" with the help of CJ Fly, and here's hoping footage of Joey and Chance performing "Wendy N Becky" together for the first time surfaces in the near future.
