Having turned in an ecstatic singalong sunset performance for an estimated 30,000 revelers on the opening day of this year’s Coachella festival, Passion Pit’s 2010 tour has been extended through the fall with the addition of a series of arena dates supporting Muse. The Muse tour will follow Passion Pit’s summer swing through their largest U.S. headline run to date and a handful of festival appearances in Canada, Japan, Australia and the UK.

In the more immediate future, Passion Pit will perform at the Earth Day Network’s 2010 Climate Rally on the National Mall in Washington DC this Sunday, April 25. Passion Pit will join a musical lineup featuring Sting, Bob Weir, The Roots, Booker T, Mavis Staples, Jimmy Cliff and more, as well as speakers ranging from the NFL’s Dhani Jones to Oscar winning director James Cameron, in commemorating the 40th anniversary of Earth Day. The 11:00 a.m. to 7:00 p.m. Climate Rally will stream live on www.earthday.org.

Originally conceived as a dorm room recording project by Michael Angelakos, Passion Pit currently consists of Angelakos, Ian Hultquist, Ayad Al Adhamy, Nate Donmoyer and Jeff Apruzzese. Its first full length album, Manners, was released in May 2009 to rave reviews and a #51 debut on the Billboard albums chart and was re-released April 13 in a deluxe format featuring multiple bonus tracks. On the strength of the irresistible hooks of “The Reeling,” “Little Secrets” and current single “Sleepyhead,” as well as a rapidly burgeoning live draw, Manners has sold over 160,000 copies since its release last spring and is closing in on a full year on the Top 200.

A: We are happy to report that the band is Muse and the song is called “Shine” — here it is to enjoy!

If the music industry was smart they’d have someone recording these cool moments professionally and releasing them as iTunes tracks or directly on the band’s website–or both. I’d buy this things like crazy. Just like when I heard Travis cover Britney Spears’ “Baby One More Time” years ago. These are brilliant moments only left for people in attendance to enjoy. What a massive waste that such brilliance gets lost after the moment is over.

And if you care–here is Travis covering Britney.

Muse is currently on tour with Silversun Pickups.

Frontman Matt Bellamy has told NME.COM he is not yet sure yet what form the record will take – and it may not appear as a conventional album.

“What will come out of that is impossible to say,” he declared. “It may just be albums, but it may be a stream of singles, or it may just be one 50-minute symphony, do you know what I mean? Who knows?”

Read the whole deal one NME.

In case you need to be reminded about their genius watch a few videos.
