This is the first time I'm covering choral works and it's getting me all hyped up since I was from a church choir for more than 10 years. Crucifixus from the mass in B minor composed by Johann Sebastian Bach was Bach's last work before he passed away and this piece is one of my favorite choral work by Bach besides Jesu, Joy of Man's Desiring. Crucifixus which means "nailed to the cross" in Latin has an extremely mysterious feel due to the fact that it is performed in a minor key and bears an extremely sad lyrics. I reckon it's best performed with strings and a Harpsichord.
This is by far the best recording I encountered in Youtube by a group of soloists, Taverner Consort & Players with Andrew Parrott as the conductor. Just hearing the bass soloist's E at 2:58 is enough to give me goosebumps.
