Macklemore does offensive thing at live performance and Stranger shits collective pants, requires apology. MIA does racist thing at live performance, and it's "on point".
Go easy on the sound person—any big artist even remotely concerned with sounding good live has a sound person that travels with them who knows exactly how to dial them in. Unless you're at the Hollywood Bowl on a warm, windless night (and even then...), or standing in exactly the right spot, amplified outdoor music usually just sounds like shit.
fixed that for ya. and mia is wack as fuck. truffle fries, anyone?
