Broken Base: Mid '90s Post-Grunge Silverchair fans vs. late '90s/'00s experimental art pop Silverchair fans.
Fan Hater: A great many have derided their first two albums as second-rate Pearl Jam knockoffs.
Fanon Discontinuity: Ask a fan of the mid-90s grunge style Silverchair if the band has released anything since their hiatis (03-06). I dare you.
Diorama falls into this for some fans.
Conversely, many fans hate Frogstomp and Freak Show for being watered-down, derivative post-grunge, but love them from Neon Ballroom on.
Growing the Beard: A gradual process they have been going through throughout their career. Their first two records see them being "Nirvana in Pyjamas", but on their third album, Neon Ballroom, you see them starting to experiment with their sound. And by the time they release Young Modern, they have successfully become Art Rock With Teeth (no mean feat in a genre with emphasis on melody and atmospherics), and being gritty, yet elegant and eclectic at once.
