How does one decide?
The most obvious way would be to look at the Pitchfork rankings of the bands' most recent albums. Wolf Parade's Expo 86 gets a respectacle but not spectacular 7.5 ("more dependable than revelatory"). Shearwater's The Golden Archipilago gets a slightly higher 7.9 ("the record is introduced by a field recording of what sounds like an island choir."). We give Shearwater the hipster edge here because their work is more pretentious.
But there are other factors to take into account as well. The opening act for Wolf Parade is called Ogre, You Asshole, and they are from Japan, which is kind of hip. But then again Shearwater's opener is the dependable Damien Jurado, whose new album also gets a 7.9 from Pitchfork ("meditations on 1950s girl-group balladry, thorny Neil Young-esque guitar rock, and cavernous chamber-pop.").
Then you must factor in that the Jackpot is infinitely hipper than the Granada, as well as a few bucks cheaper.
So where will the boys spend their Friday evening?
Richard: "I'll be at the Replay to see the Danish metal band with the unpronounceable name."
