Modest Mouse will be heading back to Australia this July for the Splendour in the Grass festival, taking place from July 29 - 31.
According to Modest Mouse's Facebook page, they will be performing on Saturday, July 30, but no word yet from the festival organizers if this is the day of the festival they will be performing on.
Side note: The ticketing page on Moshtix listing the lineup, has notes next to some bands stating whether the show is that band's only Australian show. There is nothing next to Modest Mouse's name, perhaps indicating that more Australian shows may be added.
