Usually, I like Tarwater a lot less than their spin-off/sister To Rococo Rot. Their music is often pretty interesting, as might be expected, but the lugubrious, Teutonic-speak vocals really don't do much for me.
A Tarwater instrumental would solve that problem, though. & while they seem pretty rare, one is the wonderfully atmospheric, spidery, twanging Yeah! (which has some chanting by way of a chorus, but none of the post-Nico vocalising).
It comes from the 2005 album The Needle Was Travelling (buy here) on morr music.
