Here's this week's question:

In 2009, the Beastie Boys cancelled their Outside Lands performance last minute (the group decided to put its focus on Adam "MCA" Yaunch's recovery from cancer rather than touring). Who replaced them on the lineup? And which artist (who also performed at Outside Lands that year) expressed disappointment (an understatement) about the switch via Twitter?
