Rehearsing My Choir is my second favorite Fiery Furnaces album next to Bitter Tea. I really have no problem with granny's voice; it's a lot more expressive then the siblings', I think.
People ask me why Blueberry Boat isn't number one... I don't know, it's mostly great, but it has a few stupid tracks that sort-of sour the flow for me... and Bitter Tea's instrumentation just packed a certain initial wallop, production-wise, that Blueberry Boat didn't.
People say Rehearsing My Choir is just inaccessible, and I get that, but to me it's just wacky Shatner-esque narration with some really great accompaniment... it stands alone from all their other albums in this respect, and that's why it isn't number one, but I honestly hope their next album does something similarly fucked-up.
