During the Three Weeks, many people have the custom of saying Tikkun Chatzot - the midnight lamentations - during the day (see Kaf HaChaim, 551:222). We not only lament the loss of our Holy Temple, but we try to rectify the root causes for losing it, particularly sinas chinam, baseless hate.
In the following clip, you'll see Cantor Ushi Blumenberg, one of the Jewish world's most promising young cantors, singing Sheyiboneh Beis Hamikdash, bmeira beyamenu - may the Holy Temple be built speedily and in our days. This is a well-known Chabad niggun chanted daily in the morning service after the recitation of korbonos, when we read about the daily sacrifices in our Holy Temple until we have the chance of actually performing them, speedily and in our days, amen!
You'll notice how rich Ushi's voice is, out in the woods by the river with no amplification or sound embellishment, may Hashem bless him with success.
