Pearl Jam debuted two new songs at a concert in Chicago on Friday (July 19). Scroll down and click ‘play’ to watch fan footage of both songs being played live.

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.

Earlier this month (July), Pearl Jam announced that they will release Lightning Bolt, produced by O’Brien, on October 15.

Lightning Bolt will be the US band’s 10th studio album and their first since 2009’s Backspacer.
