Inspired by this thread, but oh so subtly different...
Was also just flicking through the Fugazi thread and got me to thinking that their albums all hit a certain level even by their own extremely high standards. Which other artists can you think of that have never over the course of their career put out an album that falls short of their own quality control level?
Let's say for the purposes of this thread, artists that have five or more studio albums (we don't need another Arcade Fire discussion thank you very much) and excluding live albums, side projects and the like.
I'll start with Tom Waits - not a single album in his catalogue that I wouldn't look forward to listening to all the way through right now:
Some of my favourite artists have had some right wobbles over the years (Bowie, Neil Young, The Cure). Others have managed to fuck it with a single installment (good one Swans with Burning World).
Any more for any more?
