Watch live as Mudhoney performs atop the Space Needle

A live feed of Mudhoney's daring performance on the top of the Space Needle today will be broadcast on YouTube. Other performers on the ticket (but not on the top of the Needle) include J. Mascis and Sera Cahoone.

The performance kicks off Sub Pop records' anniversary weekend. Tomorrow night, Sub Pop artist Eugene Mirman will host a comedy event and benefit for local nonproftis including Northwest Harvest at the Moore. Saturday will see a takeover of the Georgetown neighborhood as Sub Pop sets up multiple stages and invites artists like Built to Spill, Shabazz Palaces, THEESatisfaction and, of course, Mudhoney.

And yes, Mudhoney will be harnessed to the Needle for safety.
