Sure, but Gareth & Tom as lyricist and songwriter have always seemed to define the core of their sound. I love all the other members and they are vital to the existence and ~Campesinos!~ness of it all but I’ve always had the sense that most of the driving force behind the sound and words has been those two.
Plus, remember the line-up was unchanged through the recording of Romance is Boring.
The biggest change for me was always the departure of Aleks right after the first US tour for RiB (the MTL stop was cancelled because of that volcano, iirc, alas). Mostly because her voice had been such a big presence complementing Gareth and the switch to Gareth’s sister Kim changed the vibe on Hello Sadness.
I miss Ollie a lot, and Jason and Rob have both been solid additions, and the recent departures of Ellen and Harriet for new things and school will definitely impact whatever they do next, but the first three (and even first four) albums have a pretty consistent line-up all things considered.
ETA: I think the quick one-two punch of those first two records in one year and the (relatively) quick follow up after that with Romance is Boring compared to the longer tours and recording processes for the fourth album and the Heat Rash 7”s makes the changes feel like they’ve been going on longer than they have. Hard to imagine that it’s only been five years since the first LP, and three since the third LP.
