Thom Gunn's lecture on Basil Bunting.
For anyone wanting an intelligent overview or an introduction to Bunting's life and work this is a good starting point. Gunn was convinced both of the quality and importance of Briggflatts, and the stature of Bunting as a poet. He does a good job of explaining why the thought so. You can listen to the whole lecture by following the link below.
If I were going to quarrel with him, since cats can look at Kings and even argue with them, I'd say he overrates Pound's influence, as everyone else does, and I wouldn't rate Canto 47 so highly. I don't think Pound got close to writing something equal to either The Waste Land or Briggflatts. I don't even think he could have written something like Villon.
