Foo Fighters are currently embarking on a tour of tiny venues after launching a contest for fans to win a private show at their home.
The eight gigs will all be played in garages to mark the release of the band's latest hit album, "Wasting Light", which was recorded in frontman Dave Grohl's garage in California.
They played a show at a fan's home close to Chicago, Illinois on Tuesday, but their planned appearance in Minneapolis-Saint Paul, Minnesota on Wednesday was postponed due to illness, according to Minneapolis' StarTribune.
It is not known which members of the band are sick. The date will be rescheduled and their next planned garage show will take place in Denver, Colorado on Monday.
