Here is a fascinating document - one of few complete recordings by the amazing Giacomo Lauri-Volpi. He was an utter egotist, but his timbre was unequaled. He could produced a sound of gigantic power and switch to a mezzavoce (reminiscent of Tagliavini - his mezzavoce that is).
A wobble had entered Lauri Volpi's voice by the early Fifties (his peak was in the Thirties and Forties) but you can still hear a voice of sublime grace mixed with a steely high range - something Del Monaco and Corelli could never achieve. If I'm honest Cetra should had given the role of Manrico to Mario Filippeschi, but alas he never recorded it.
Unsurprisingly the work is cut, and it's typical narrow Cetra sound, but nonetheless if you like Il Trovatore as much as I do (plot aside) it is a recording worth getting with the bonus of Mancini as Leonora and Tagliabue as Di Luna.
