My girlfriend put Vanden Plas's Christ 0 (their latest album) on my phone, and I absolutely love their cover of Gethsemane from Jesus Christ Superstar.
Now, I've never been into musicals, but recently I've found myself becoming quite interested in them, at least the Lloyd-Weber ones. So I checked around for good performances on YouTube and found some good versions of it, but this one just blows me away. Clinically precise, lots of pathos, and a lot of 'soul'.
The only thing that I don't like is the pronunciation of a handful of T's, but that's extremely minor. The guy, for my money, is flat out amazing.

You obviously have to be sympathetic to the fact this isn't a regular genre; these are actors as well as singers, so there's way more drama in the performance than you typically get elsewhere.

Anyhow, I give you Steve Balsamo:
