Ok. I'll just say it.
I am obsessed with Strauss' Elektra. Craig and I checked out the DVD and watched it a couple of weeks ago (The 1989 Eva Marton Vienna Staatsoper). Most of the scenes can also be found on youtube.
It can be angular yet voluptuous--and Eva Marton is a beast...basically it requires shouting for two hours over a full orchestra with constant brass.
The opening line "Allein! Weh, ganz allein" gets me every time.
