It might sound like a dessert, but Pinkpop is actually one of Europe's bigger summer festivals -- and this year's lineup was no exception, boasting three days of huge stars across the pop and rock spectrum that culminated last night (May 28) with a 23-song set from Bruce Springsteen, who was joined by Mumford and Sons for an encore performance of 'Hungry Heart.'

It was an all around big day for Mumford and Sons, who used their own Pinkpop set to announce the completion of their hotly anticipated second studio album. After frontman Marcus Mumford told the crowd that recording was finished, keyboard player Ben Lovett added that fans could expect a September 24 release -- jibing with the band's earlier statements about wanting to get the record out before the end of the year.

While this fan recording of the band's Springsteen summit is fairly dodgy in terms of audio-visual fidelity -- and the person who uploaded it seems to have done so out of anger, referring to Mumford and Sons' contribution as a "disgraceful performance" -- it's still an interesting watch, and it's always good to see the Boss mixing it up with younger artists. Perhaps there's still time to arrange a last-minute collaboration on the new record?
