Like a brisk chill in the air the morning after an 80 degree evening, Yeezy season creeps up with more subtlety every year. Today marks the official turn of the seasons, and we've gotten the audio equivalent of two crunchy leaves falling to the concrete: the full CDQ of Theophilus London's "Do Girls," arranged by Kanye West, and a snippet of Tyga's "40 Mil," co-produced by Kanye West and Mike Dean. We've heard the Theo cut in a few forms since January, and Tyga has teased at least one other single that could've had West's fingerprints on it--with both these albums boasting Kanye West executive producer credits, you'll have to keep your ears open to hear which way the wind blows next. Check out Kanye's surprise 20-minute sermon at this week's AAHH! Fest in Chicago.
