Pearl Jam debuted two new songs at a concert in Chicago on July 19, NME reports. The songs' titles are "Lightning Bolt" and "Future Days."
Both tracks are featured in the band's upcoming album "Lightning Bolt," due to release on October 15.
The band were just seven songs into their gig at Chicago's Wrigley Field, Consequence of Sound reports, when torrential rain forced them offstage.
After a delay of three hours, the band were finally able to return and rewarded the crowd by playing two previously unheard songs from their forthcoming album "Lightning Bolt": the title track and "Future Days." On the latter, the band were joined by producer Brendan O'Brien on keyboards.
"Lightning Bolt" will be the US band's 10th studio album and their first since 2009's "Backspacer." Speaking earlier this year, guitarist Mike McCready said of the new album: "I would say as a cliché answer it's kind of a logical extension of what 'Backspacer' was. But I think there's a little bit more experimental stuff going on. There's a Pink Floyd vibe to some of it, there's a punk rock edge to other stuff."
