Query: Disappointing

I collect lieder recitals by contraltos and mezzo-sopranos. This is not one I'll keep. Zakai's voice was plainly not up to the job. Much of it I found unlistenable. Why any contralto would waste her time on Webern is beyond me. She doesn't do anything for him but he's beyond redemption anyway. The producers have thrown in some Handel, which isn't too bad, possibly as an afterthought to appease the listener. Notes are minimal and song texts are not provided. But that's okay as you don't need them.
