Pretty sure it's not them since they just played there like a month or so ago. I don't think there is an opening band.
It does say "with a special guest," which is standard language on the venue's website for "opener TBA." I'm sure there'll be somebody, but Dino Jr would probably be hoping for too much.
Then again, on the National's facebook page someone asked why MBV was playing there instead of somewhere else and they said Dino Jr. told them it was the best venue in the country, so maybe??
