The longer it ages, the more Odd Future de facto leader Tyler The Creator's Bastard becomes more indicative of hip-hop's cultural malaise, to a point where it almost hurts to listen to it. Almost. The lyrics (in all their vulgar glory), the no-fucks-given attitude, the crunchy homemade beats; it's the sound of frustration, of innovation.

At the time of Bastard's release, it felt like the big rap stars had grown fat and complacent, making the mainstream increasingly thin, leaving little to no room for new pioneers. The kids that make up the collective that is Odd Future were born out of these rigid parameters, and emerged screaming, kicking, and wanting to light everything on fire after carving upside-down crosses into it.

Almost anthropomorphically, Tyler growls and moans about his derelict dad, and his disgust with rap blogs. Four years later, Odd Future have an army of youngsters who might not be upheaving the throne, but still continue to put a little sweat on the brows of those who still aren't sure what to make of them. —Alysa Lechner
