"Au fond du Temple Sant" from Bizet's "The Pearl Fishers" -- can make every hair on my body stand up and take notice.

Vivaldi, Mozart (especially his "Requiem"), Telemann, "Sheherezade" by Rimski-Korsakoff,
Wagner ("Die Meistersinger"), Richard Strauss.

There's a Scarlatti harpsichord LP I bought back in the '60s that I would LOVE to find a CD of -- that particular recording, not just the material, of course.
