Very true. The ones with Stanier are also pretty great. But that old stuff that’s got more post-punk going on is definitely Of This Parish.
I think the “seriousness” accusation is kind of off mark, but an easy observation at a surface level. They’re definitely serious music without taking themselves seriously as a group. There’s plenty of war stories with them and the Melvins, TJL, GvsBs etc that don’t indicate taking themselves that seriously. Also the “weird” tracks on Betty are a deliberate attempt to lean into that. There’s an interview with John somewhere where he recounts a photographer asking them to do a shoot doing pushups in a boxing ring. The band told him to fuck off and ended up doing that laughing hanging off a pipe photo instead. Also the “shorts and crew cuts” were kind of bit as well. There was definitely no band stylist but Page told me the vaguely downtown skateboarder aesthetic they dress as anyway was kind of locked in to not appear to look like hipsters or metalheads. As was the bright pink ESP.
