I love both. It's very hard to decide.
i'm from barcelona is one of the most fun shows i have ever seen.
my view is pretty subjective and not really based on music just how much fun i had while seeing them.
seen them both, polyphonic spree all the way baby! but both are great :)
Spree it to me, I just can't get into the 'barca boys.
I like IMB, but I LOVE Polyphonic Spree
Musically, the Polyphonic Spree are much, much better.
