SOUNDGARDEN helped kick off the 2014 National Football League season by performing on Thursday, September 4 outside Seattle's CenturyLink Field as part of the 2014 NFL Kickoff. The free performance took place before the game between the Seahawks and Green Bay Packers and was seen on the 60-minute pre-game show airing from 4:30 p.m. to 5:30 p.m. PT on NBC and the NFL network.

SOUNDGARDEN's co-headlining summer trek with NINE INCH NAILS, which kicked off on July 19 in Las Vegas, concluded on August 30 in Auburn, Washington.
