Fans of Supergrass (pictured) and Year Long Disaster will reap an unexpected benefit from the postponement of the Foo Fighters' July 14 and 15 Red Rocks shows (click here for those details). While Dave Grohl is too sick to perform on those dates, the aforementioned bands, who are opening for the Foo on the current tour, are in perfect health -- and rather than take extra nights off, they've opted to schedule a fill-in date at the Larimer Lounge on the 14th. Grease Machine is the lucky Denver group to kick off the evening at 9 p.m., followed by Year Long Disaster at 10 p.m. and Supergrass at 11 p.m. The show promises to be sick. -- Michael Roberts
