For those saying Pretty Lights sucks. That's only half true. Seen him too many times live for it to be fun anymore. I'm tired of hearing the same setlist save for 2 or 3 songs he likes to switch up. I can agree that he's not the best to go see live, but you gotta check it out at least once. That being said, the production of his live show is on a whole other level entirely right now.
The dude is a genius at sample mapping. Even if he's not the "best" he's got a personal touch that makes his music his own (which takes talent), and infectious for hoards of EDM fans. You can hate on him all you want, but you know its the truth.
PL > ASAP in the live element. Especially if you've never been to a Pretty Lights show. You'll get the hip-hop, the nearly naked girls, and the lights. Easy decision imo.
PS: I've heard ASAP lip syncs.
