Cole, Wiz Khalifa, Evidence, Murs, Aloe Blacc, Planet Asia, Blu, The Alchemist, and 9th Wonder. Most recently in 2014, Fashawn performed the entrance theme to WBO welterweight champion Timothy Bradley's rematch against Manny Pacquiao, and was introduced by Nas to a sold-out crowd at SXSW where he performed material from his upcoming second album The Ecology.
