No idea what happened with Franz, they got off to a better start than most any other indie band of the 2000s but seemed to run out of steam by the third album commercially, although I find it quite decent myself. They shouldn't be that low down in the lineup
They headlined Truck in 2017 and now they’re a sub or third down next year so they seem to be okay with lower slots. Shockingly low slot at Boardmasters too.
