(Neumos) Compton's YG (that's Young Gangsta) burst onto the charts with his catchy, disrespectful pop-rap hit "Toot It and Boot It" in 2009, but in the years since, he and his Pu$haz Ink label crew have blown up with their stripped-down-yet-turnt-up "ratchet music" sound. Built on producer/DJ Mustard's sparse, snappy, hard-knocking beats (see Tyga's ubiquitous "Rack City" for a prime example) and YG's flexin', VIP-section baller lyrics, it's young LA's post–N.W.A, post–Dr. Dre party music—set in luxury cars or in the club, but still very much rooted in and affiliated with the area's gang culture and tradition. A quick listen to YG's recent Just Re'd Up 2 mixtape should be enough to determine whether this is all a fun time or a "ratchet mess" for you. See also My Philosophy.
