Thanks to the fantastamagical Tom Kirk:
Hey. Muse are set to return to the States for the month of April. The band will be playing campus concerts across the country. We are very pleased to confirm that Razor Light will be supporting. Sorry its taking time to announce the list of dates, but all will be confirmed in a matter of days on muse.mu.
We already (kind of) new this, but it's good to see it confirmed.
