Katy Perry Closes Out Round-the-Clock YouTube Stream With Intimate L.A. Concert

Katy Perry has been going back to school with her new album Witness -- at least, that's what her time in the Big Brother-style house she locked herself in over the past 72 hours seems to have suggested.

In there, she's subjected herself to several conversations and activities (including a one-hour Viceland therapy session on Friday and a very intense and fiery dinner discussion featuring the likes of Caitlyn Jenner, Amanda Seales and Yung Skeeter on Sunday night) that focuses her rhetoric on remorse for past cultural appropriation gaffes, asking questions about subjects she's too privileged to be fully informed upon and trying in general to expand her mind. It's rubbed many a culture vulture the wrong way, particularly as Witness's initial launch via lead single "Chained to the Rhythm" came with such a sure-headed future intent for "Purposeful Pop" (Perry's words back in February).
