While it originally looked like Modest Mouse set was not going to be included in the list of acts Coachella would be streaming tonight, an 11th hour campaign organized by board member jplan74 seems to have changed the festival organizers minds.
Modest Mouse's set tonight will be streamed, just not live. The band's set will be shown on Channel 2 of the Coachella YouTube stream at 9pm Pacific Time tonight.
Thanks to all that helped out.
